jQuery custom content scroller

jQuery custom content scroller

Highly customizable custom scrollbar jQuery plugin. Features include vertical and/or horizontal scrollbar(s), adjustable scrolling momentum, mouse-wheel (via jQuery mousewheel plugin), keyboard and touch support, ready-to-use themes and customization via CSS, RTL direction support, option parameters for full control of scrollbar functionality, methods for triggering actions like scroll-to, update, destroy etc., user-defined callbacks and more.

Current version 3.1.5 (Changelog)
Upgrading from version 2

When upgrading from version 2.x to 3.x it’s important to use version 3 CSS and .png files. Version 3 is backwards compatible but it’s also a huge overhaul. One significant change is that you don’t need to call the update method manually (the script does it automatically). For more info see changelog.

Version 2 is still maintained and updated here.


How to use it

Get started by downloading the archive which contains the plugin files (and a large amount of HTML demos and examples). Extract and upload jquery.mCustomScrollbar.concat.min.js, jquery.mCustomScrollbar.css and mCSB_buttons.png to your web server (alternatively you can load plugin files from a CDN).

Instead of hosting the plugin files on your web server, you can load them directly from a CDN like jsdelivr, Github etc.

  • jsdelivr versioned/minified
    • //cdn.jsdelivr.net/jquery.mcustomscrollbar/3.0.6/jquery.mCustomScrollbar.concat.min.js
    • //cdn.jsdelivr.net/jquery.mcustomscrollbar/3.0.6/jquery.mCustomScrollbar.min.css
    • //cdn.jsdelivr.net/jquery.mcustomscrollbar/3.0.6/mCSB_buttons.png
  • Github latest/minified

    • //malihu.github.io/custom-scrollbar/jquery.mCustomScrollbar.min.css
    • //malihu.github.io/custom-scrollbar/mCSB_buttons.png


HTML

Include jquery.mCustomScrollbar.css in the head tag your HTML document (more info)

jquery.mCustomScrollbar.css contains the styling of the custom scrollbar and themes. It should normally be included in the head tag of your html (typically before any script tags). If you wish to reduce http requests and/or have all your website stylesheet in a single file, you should move/copy scrollbars styling in your main CSS document.

mCSB_buttons.png contains all the button arrows (up, down, left and right) as image sprites for all scrollbar themes. The plugin archive contains the PSD source (source-files/mCSB_buttons.psd) so you can change them or add your own. This file should be in the same directory with plugin stylesheet.


<link rel="stylesheet" href="/path/to/jquery.mCustomScrollbar.css" />

Include jQuery library (if your project doesn’t use it already) and jquery.mCustomScrollbar.concat.min.js in the head tag or at the very bottom of your document, just before the closing body tag

Some frameworks and CMS include jQuery library in the head tag to make sure it’s loaded when other scripts request it. Usually, including .js files on the bottom of the HTML document (just before the closing body tag) is recommended for better performance. In any case, jQuery must be included first, before plugin scripts.


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="/path/to/jquery.mCustomScrollbar.concat.min.js"></script>

CSS

The element(s) you want to add scrollbar(s) should have the typical CSS properties of an overflowed block which are a height (or max-height) value, an overflow value of auto (or hidden) and content long enough to require scrolling. For horizontal scrollbar, the element should have a width (or max-width) value set.

If you prefer to set your element’s height/width via javascript, you can use the setHeight/setWidth option parameters.

Initialization

Initialize via javascript

After files inclusion, call mCustomScrollbar function on the element selector you want to add the scrollbar(s)

<script>
    (function($){
        $(window).on("load",function(){
            $(".content").mCustomScrollbar();
        });
    })(jQuery);
</script>

more info

The code is wrapped in (function($){ ... })(jQuery);. This ensures no conflict between jQuery and other libraries using $ shortcut (see Avoiding Conflicts with Other Libraries for more info). The plugin function is called in $(window).on("load") so it executes after all page elements (like images) are loaded.

You can change the function selector ".content" to any selector you want (an element id, class name, js variable etc.). For instance, if you want custom scrollbars to apply on the element with id content-1, you simply do:

$("#content-1").mCustomScrollbar();

You may also have multiple selectors by inserting comma separated values

$(".content,#content-1").mCustomScrollbar();

The above code adds custom scrollbars to a)every element with class name content and b)the element with id content-1.

Additionally, you may want to call mCustomScrollbar multiple times within a page in order to set different options (configuration and option parameters explained below) for each selector

<script>
  (function($){
    $(window).on("load",function(){
      $("#vertical-content").mCustomScrollbar({
        theme:"light-3",
        scrollButtons:{
          enable:true
        }
      });
      $("#horizontal-content").mCustomScrollbar({
        axis:"x",
        theme:"3d"
      });
    });
  })(jQuery);
</script>

Initialize via HTML

Add the class mCustomScrollbar to any element you want to add custom scrollbar(s) with default options. Optionally, set its axis via the HTML data attribute data-mcs-axis (e.g. "x" for horizontal and "y" for vertical) and its theme via data-mcs-theme. For example:

<div class="mCustomScrollbar" data-mcs-theme="dark">
  <!-- your content -->
</div>

Basic configuration & option parameters

axis

By default, the script applies a vertical scrollbar. To add a horizontal or 2-axis scrollbars, invoke mCustomScrollbar function with the axis option set to "x" or "yx" respectively

$(".content").mCustomScrollbar({
    axis:"x" // horizontal scrollbar
});
$(".content").mCustomScrollbar({
    axis:"yx" // vertical and horizontal scrollbar
});

theme

To quickly change the appearance of the scrollbar, set the theme option parameter to any of the ready-to-use themes available in jquery.mCustomScrollbar.css, for example:

$(".content").mCustomScrollbar({
    theme:"dark"
});

Configuration

You can configure your scrollbar(s) using the following option parameters on mCustomScrollbar function
Usage $(selector).mCustomScrollbar({ option: value });

setWidth: false
Set the width of your content (overwrites CSS width), value in pixels (integer) or percentage (string).
setHeight: false
Set the height of your content (overwrites CSS height), value in pixels (integer) or percentage (string).
setTop: 0
Set the initial css top property of content, accepts string values (css top position).
Example: setTop: "-100px".
setLeft: 0
Set the initial css left property of content, accepts string values (css left position).
Example: setLeft: "-100px".
axis: "string"
Define content’s scrolling axis (the type of scrollbars added to the element: vertical and/of horizontal).
Available values: "y", "x", "yx".

  • axis: "y" – vertical scrollbar (default)
  • axis: "x" – horizontal scrollbar
  • axis: "yx" – vertical and horizontal scrollbars
scrollbarPosition: "string"
Set the position of scrollbar in relation to content.
Available values: "inside", "outside".
Setting scrollbarPosition: "inside" (default) makes scrollbar appear inside the element. Setting scrollbarPosition: "outside" makes scrollbar appear outside the element. Note that setting the value to "outside" requires your element (or parent elements) to have CSS position: relative (otherwise the scrollbar will be positioned in relation to document’s root element).
scrollInertia: integer
Set the amount of scrolling momentum as animation duration in milliseconds.
Higher value equals greater scrolling momentum which translates to smoother/more progressive animation. Set to 0 to disable.
autoDraggerLength: boolean
Enable or disable auto-adjusting scrollbar dragger length in relation to scrolling amount (same bahavior with browser’s native scrollbar).
Set autoDraggerLength: false when you want your scrollbar to (always) have a fixed size.
autoHideScrollbar: boolean
Enable or disable auto-hiding the scrollbar when inactive.
Setting autoHideScrollbar: true will hide the scrollbar(s) when scrolling is idle and/or cursor is out of the scrolling area.
Please note that some special themes like “minimal” overwrite this option.
autoExpandScrollbar: boolean
Enable or disable auto-expanding the scrollbar when cursor is over or dragging the scrollbar.
alwaysShowScrollbar: integer
Always keep scrollbar(s) visible, even when there’s nothing to scroll.

  • alwaysShowScrollbar: 0 – disable (default)
  • alwaysShowScrollbar: 1 – keep dragger rail visible
  • alwaysShowScrollbar: 2 – keep all scrollbar components (dragger, rail, buttons etc.) visible
snapAmount: integer
Make scrolling snap to a multiple of a fixed number of pixels. Useful in cases like scrolling tabular data, image thumbnails or slides and you need to prevent scrolling from stopping half-way your elements. Note that your elements must be of equal width or height in order for this to work properly.
To set different values for vertical and horizontal scrolling, use an array: [y,x]
snapOffset: integer
Set an offset (in pixels) for the snapAmount option. Useful when for example you need to offset the snap amount of table rows by the table header.
mouseWheel:{ enable: boolean }
Enable or disable content scrolling via mouse-wheel.
mouseWheel:{ scrollAmount: integer }
Set the mouse-wheel scrolling amount (in pixels). The default value "auto" adjusts scrolling amount according to scrollable content length.
mouseWheel:{ axis: "string" }
Define the mouse-wheel scrolling axis when both vertical and horizontal scrollbars are present.
Set axis: "y" (default) for vertical or axis: "x" for horizontal scrolling.
mouseWheel:{ preventDefault: boolean }
Prevent the default behaviour which automatically scrolls the parent element when end or beginning of scrolling is reached (same bahavior with browser’s native scrollbar).
mouseWheel:{ deltaFactor: integer }
Set the number of pixels one wheel notch scrolls. The default value “auto” uses the OS/browser value.
mouseWheel:{ normalizeDelta: boolean }
Enable or disable mouse-wheel (delta) acceleration. Setting normalizeDelta: true translates mouse-wheel delta value to -1 or 1.
mouseWheel:{ invert: boolean }
Invert mouse-wheel scrolling direction. Set to true to scroll down or right when mouse-wheel is turned upwards.
mouseWheel:{ disableOver: [array] }
Set the tags that disable mouse-wheel when cursor is over them.
Default value:
["select","option","keygen","datalist","textarea"]
scrollButtons:{ enable: boolean }
Enable or disable scrollbar buttons.
scrollButtons:{ scrollAmount: integer }
Set the buttons scrolling amount (in pixels). The default value "auto" adjusts scrolling amount according to scrollable content length.
scrollButtons:{ scrollType: "string" }
Define the buttons scrolling type/behavior.

  • scrollType: "stepless" – continuously scroll content while pressing the button (default)
  • scrollType: "stepped" – each button click scrolls content by a certain amount (defined in scrollAmount option above)
scrollButtons:{ tabindex: integer }
Set a tabindex value for the buttons.
keyboard:{ enable: boolean }
Enable or disable content scrolling via the keyboard.
The plugin supports the directional arrows (top, left, right and down), page-up (PgUp), page-down (PgDn), Home and End keys.
keyboard:{ scrollAmount: integer }
Set the keyboard arrows scrolling amount (in pixels). The default value "auto" adjusts scrolling amount according to scrollable content length.
keyboard:{ scrollType: "string" }
Define the keyboard arrows scrolling type/behavior.

  • scrollType: "stepless" – continuously scroll content while pressing the arrow key (default)
  • scrollType: "stepped" – each key release scrolls content by a certain amount (defined in scrollAmount option above)
contentTouchScroll: integer
Enable or disable content touch-swipe scrolling for touch-enabled devices.
To completely disable, set contentTouchScroll: false.
Integer values define the axis-specific minimum amount required for scrolling momentum (default: 25).
documentTouchScroll: boolean
Enable or disable document touch-swipe scrolling for touch-enabled devices.
advanced:{ autoExpandHorizontalScroll: boolean }
Auto-expand content horizontally (for "x" or "yx" axis).
If set to true, content will expand horizontally to accommodate any floated/inline-block elements.
Setting its value to 2 (integer) forces the non scrollHeight/scrollWidth method. A value of 3 forces the scrollHeight/scrollWidth method.
advanced:{ autoScrollOnFocus: "string" }
Set the list of elements/selectors that will auto-scroll content to their position when focused.
For example, when pressing TAB key to focus input fields, if the field is out of the viewable area the content will scroll to its top/left position (same bahavior with browser’s native scrollbar).
To completely disable this functionality, set autoScrollOnFocus: false.
Default:
"input,textarea,select,button,datalist,keygen,a[tabindex],area,object,[contenteditable='true']"
advanced:{ updateOnContentResize: boolean }
Update scrollbar(s) automatically on content, element or viewport resize.
The value should be true (default) for fluid layouts/elements, adding/removing content dynamically, hiding/showing elements etc.
advanced:{ updateOnImageLoad: boolean }
Update scrollbar(s) automatically each time an image inside the element is fully loaded.
Default value is auto which triggers the function only on "x" and "yx" axis (if needed).
The value should be true when your content contains images and you need the function to trigger on any axis.
advanced:{ updateOnSelectorChange: "string" }
Update scrollbar(s) automatically when the amount and size of specific selectors changes.
Useful when you need to update the scrollbar(s) automatically, each time a type of element is added, removed or changes its size.
For example, setting updateOnSelectorChange: "ul li" will update scrollbars each time list-items inside the element are changed.
Setting the value to true, will update scrollbars each time any element is changed.
To disable (default) set to false.
advanced:{ extraDraggableSelectors: "string" }
Add extra selector(s) that’ll release scrollbar dragging upon mouseup, pointerup, touchend etc.
Example: extraDraggableSelectors: ".myClass, #myID"
advanced:{ releaseDraggableSelectors: "string" }
Add extra selector(s) that’ll allow scrollbar dragging upon mousemove/up, pointermove/up, touchend etc.
Example: releaseDraggableSelectors: ".myClass, #myID"
advanced:{ autoUpdateTimeout: integer }
Set the auto-update timeout in milliseconds.
Default timeout: 60

Plugin methods

Ways to execute various plugin actions programmatically from within your script(s).

update

Usage $(selector).mCustomScrollbar("update");

Call the update method to manually update existing scrollbars to accommodate new content or resized element(s). This method is by default called automatically by the script (via updateOnContentResize option) when the element itself, its content or scrollbar size changes.

view examples

/* initialize plugin with auto-update options disabled */
$(selector).mCustomScrollbar({
  advanced:{
    updateOnContentResize: false,
    updateOnImageLoad: false
  }
});

/* at some point in your js script/code update scrollbar manually */
$(selector).mCustomScrollbar("update");

scrollTo

Usage $(selector).mCustomScrollbar("scrollTo",position,options);

Call the scrollTo method to programmatically scroll the content to the position parameter (demo).

position parameter

Position parameter can be:

  • "string"
    • e.g. element selector: "#element-id"
    • e.g. special pre-defined position: "bottom"
    • e.g. number of pixels less/more: "-=100"/"+=100"
  • integer
    • e.g. number of pixels: 100
  • [array]
    • e.g. different y/x position: [100,50]
  • object/function
    • e.g. jQuery object: $("#element-id")
    • e.g. js object: document.getelementbyid("element-id")
    • e.g. function: function(){ return 100; }

Pre-defined position strings:

  • "bottom" – scroll to bottom
  • "top" – scroll to top
  • "right" – scroll to right
  • "left" – scroll to left
  • "first" – scroll to the position of the first element within content
  • "last" – scroll to the position of the last element within content

view examples

Scroll to element with id “#el-1″

$(selector).mCustomScrollbar("scrollTo","#el-1");

Scroll to top

$(selector).mCustomScrollbar("scrollTo","top");

Scroll by 100 pixels down or right

var val=100;
$(selector).mCustomScrollbar("scrollTo","-="+val);

Scroll by 100 pixels up or left

$(selector).mCustomScrollbar("scrollTo","+=100");

Scroll by 100 pixels down and by 50 pixels right

$(selector).mCustomScrollbar("scrollTo",["-=100","-=50"]);

Scroll to the fifth paragraph

$(selector).mCustomScrollbar("scrollTo",$("p:eq(4)"));

Scroll to the last element within your content

$(selector).mCustomScrollbar("scrollTo","last");

Scroll to some variable value

var val=document.getelementbyid("element-id");
$(selector).mCustomScrollbar("scrollTo",val);

Scroll to 300 pixels

$(selector).mCustomScrollbar("scrollTo",300);

Method options

scrollInertia: integer
Scroll-to duration, value in milliseconds.
Example:
$(selector).mCustomScrollbar("scrollTo","bottom",{
    scrollInertia:3000
});
scrollEasing: "string"
Scroll-to animation easing, values: "linear", "easeOut", "easeInOut".
Example:
$(selector).mCustomScrollbar("scrollTo","bottom",{
    scrollEasing:"easeOut"
});
moveDragger: boolean
Scroll scrollbar dragger (instead of content).
Example:
$(selector).mCustomScrollbar("scrollTo",80,{
    moveDragger:true
});
timeout: integer
Set a timeout for the method (the default timeout is 60 ms in order to work with automatic scrollbar update), value in milliseconds.
Example:
$(selector).mCustomScrollbar("scrollTo","top",{
    timeout:1000
});
callbacks: boolean
Trigger user defined callbacks after scroll-to completes.
Example:
$(selector).mCustomScrollbar("scrollTo","left",{
    callbacks:false
});

stop

Usage $(selector).mCustomScrollbar("stop");

Stops any running scrolling animations (usefull when you wish to interupt a previously scrollTo method call).

disable

Usage $(selector).mCustomScrollbar("disable");

Calling disable method will temporarily disable the scrollbar (demo). Disabled scrollbars can be re-enable by calling the update method.

To disable the scrollbar and reset its content position, set the method’s reset parameter to true

$(selector).mCustomScrollbar("disable",true);

view examples

/* initialize plugin */
$(selector).mCustomScrollbar();

/* at some point in your js script/code disable scrollbar */
$(selector).mCustomScrollbar("disable");

/* re-enable scrollbar as needed */
$(selector).mCustomScrollbar("update");

destroy

Usage $(selector).mCustomScrollbar("destroy");

Calling destroy method will completely remove the custom scrollbar and return the element to its original state (demo).

view examples

/* initialize plugin */
$(selector).mCustomScrollbar();

/* at some point in your js script/code destroy scrollbar */
$(selector).mCustomScrollbar("destroy");

Scrollbar styling & themes

You can design and visually customize your scrollbars with pure CSS, using jquery.mCustomScrollbar.css which contains the default/basic styling and all scrollbar themes.

The easiest/quickest way is to select a ready-to-use scrollbar theme. For example:

$(selector).mCustomScrollbar({
  theme:"dark"
});

View all ready-to-use themes

You can modify the default styling or any theme either directly in jquery.mCustomScrollbar.css or by overwriting the CSS rules in another stylesheet.

Creating a new scrollbar theme

Create a name for your theme (e.g. “my-theme”) and set it as the value of the theme option

$(selector).mCustomScrollbar({
    theme:"my-theme"
});

Your element will get the class “mCS-my-theme” (your theme-name with “mCS” prefix), so you can create your CSS using the .mCS-my-theme in your rules. For instance:

.mCS-my-theme.mCSB_scrollTools .mCSB_dragger .mCSB_dragger_bar{ background-color: red; }
.mCS-my-theme.mCSB_scrollTools .mCSB_draggerRail{ background-color: white; } 
/* and so on... */

In the same manner you can clone any existing theme (e.g. “dark”), change its selector (e.g. .mCS-dark) to your own theme name (e.g. .mCS-my-theme) and modify its CSS rules.

Scrollbar markup

The plugin applies specific id (unique) and/or classes to every scrollbar element/component, meaning that you can target and modify any scrollbar in more than one ways.

For example, every element with a scrollbar gets a unique class in the form of _mCS_1, _mCS_2 etc. Every scrollbar container element gets a unique id in the form of mCSB_1_scrollbar_vertical, mCSB_2_scrollbar_vertical etc. Every scrollbar dragger gets a unique id in the form of mCSB_1_dragger_vertical, mCSB_2_dragger_vertical etc. in addition to the class mCSB_dragger. All these mean that you can do stuff like:

._mCS_1 .mCSB_dragger .mCSB_dragger_bar{ background-color: red; }

._mCS_2 .mCSB_dragger .mCSB_dragger_bar{ background-color: green; }

#mCSB_3_dragger_vertical .mCSB_dragger_bar{ background-color: blue; }

#mCSB_1_scrollbar_vertical .mCSB_dragger{ height: 100px; }

#mCSB_1_scrollbar_horizontal .mCSB_dragger{ width: 100px; }

.mCSB_1_scrollbar .mCSB_dragger .mCSB_draggerRail{ width: 4px; }

Custom scrollbar layout

User-defined callbacks

You can trigger your own js function(s) by calling them inside mCustomScrollbar callbacks option parameter

$(".content").mCustomScrollbar({
    callbacks:{
        onScroll:function(){
            myCustomFn(this);
        }
    }
});

function myCustomFn(el){
    console.log(el.mcs.top);
}

In the example above, each time a scroll event ends and content has stopped scrolling, the content’s top position will be logged in browser’s console. There are available callbacks for each step of the scrolling event:

  • onScrollStart – triggers the moment a scroll event starts
  • whileScrolling – triggers while scroll event is running
  • onScroll – triggers when a scroll event completes
  • onTotalScroll – triggers when content has scrolled all the way to bottom or right
  • onTotalScrollBack – triggers when content has scrolled all the way back to top or left

You can set an offset value (pixels) for both onTotalScroll and onTotalScrollBack by setting onTotalScrollOffset and onTotalScrollBackOffset respectively (view example).

The following will trigger the callback function when content has scrolled to bottom minus 100 pixels

$(".content").mCustomScrollbar({
    callbacks:{
        onTotalScroll:function(){
            console.log("scrolled to bottom");
        },
    onTotalScrollOffset:100
    }
});

By default, onTotalScroll and onTotalScrollBack callbacks are triggered repeatedly. To prevent multiple calls when content is within their offset, set alwaysTriggerOffsets option to false (view example).

$(".content").mCustomScrollbar({
    callbacks:{
        onTotalScroll:function(){
            console.log("scrolled to bottom");
        },
    onTotalScrollOffset:100,
    alwaysTriggerOffsets:false
    }
});

Additional callbacks:

Returning values

The script returns a number of values and objects related to scrollbar that you can use in your own functions

  • this – the original element containing the scrollbar(s)
  • this.mcs.content – the original content wrapper as jquery object
  • this.mcs.top – content’s top position (pixels)
  • this.mcs.left – content’s left position (pixels)
  • this.mcs.draggerTop – scrollbar dragger’s top position (pixels)
  • this.mcs.draggerLeft – scrollbar dragger’s left position (pixels)
  • this.mcs.topPct – content vertical scrolling percentage
  • this.mcs.leftPct – content horizontal scrolling percentage
  • this.mcs.direction – content’s scrolling direction (y or x)

view examples

Load more content when scrolled to bottom

$(selector).mCustomScrollbar({
    callbacks:{
        onTotalScroll:function(){
            this.mcs.content.append("...");
        }
    }
});

Run code when at least half of the content is scrolled

$(selector).mCustomScrollbar({
    callbacks:{
        whileScrolling:function(){
            var pct=this.mcs.topPct;
            if(pct>=50){
              /* do something... */
            }
        }
    }
});

Plugin-specific jQuery expressions

$("#myID:mcsInView")
Select element(s) in your content that are within scrollable viewport.
As condition: $("#myID").is(":mcsInView");
$(".content:mcsOverflow")
Select overflowed element(s) with visible scrollbar.
As condition: $(".content").is(":mcsOverflow");
$("#myID:mcsInSight")
$("#myID:mcsInSight(exact)")
Select element(s) in your content that are in view of the scrollable viewport. Using the exact parameter will include elements that have any part of them (even 1 pixel) in view of the scrollable viewport.
As condition: $("#myID").is(":mcsInSight");, $("#myID").is(":mcsInSight(exact)");

    Hello Malihu,

    When the HTML contents are coming from ajax response, the scroll option is not working as it was suppose to start from bottom.

    The same thing is working for static contents

    I am using the code like below,

    $(window).load(function(){

    $(“.ut_chmid”).mCustomScrollbar({
    autoHideScrollbar:false,
    });

    $(“.ut_chmid”).mCustomScrollbar(“scrollTo”,”bottom”, {
    scrollInertia:10,
    live: true
    });

    });

    I tried with ” live: true ” parameters, but no luck….

    I am waiting for your reply.

    Thanks,

    Hi. Is this plugin compatible with any free paralax plugin? I’ve tried to use it with Skrollr and they don’t work together. I get either one to work, or the other. It might be because they are both using the same methods to customise scrolling on the page.

    The result looks like this (testing page): http://eso-community.net/page/scroller

    If i disable this line it works:
    <script src="https://cdnjs.cloudflare.com/ajax/libs/malihu-custom-scrollbar-plugin/3.0.9/jquery.mCustomScrollbar.concat.min.js"></script>

    By “it works” I mean the parallax plugin works, but not the smooth scrolling plugin.

    Is there any way to make them compatible? Maybe make sure they load at different times or somehow their effects on the page stay separated.

    Hi Malihu,

    I was wondering if u have experience with combining your (AWESOME) scrollbar plugin and ScrollSpy. The ScrollSpy plugin is for automatically updating nav targets based on scroll position but it doesn’t work anymore when I implement your plugin code into my project. Do you have a solution or do you know the answer?

    Best regards,

    Brendan

    Hi Malihu,

    Great job with the stuff here, and the design is awesome too!

    I tried to find something, or edit the CSS, but wasn’t able to figure it out. I need your help, please.
    When I click and drag the ... dragger_bar, when I move the cursor outside of the container while dragging, it makes the whole scrollbar disappear in fade (I assume it’s opacity 0), but I wasn’t able to find what exactly causes it, and how to disable it. Can you give me a hint?

    Hi, I love your scroller, it really something to my site. I do have a problem, which I can’t fix! I have a slick thumbnail slider on the page, which opens to a Colorbox carousel. In most browsers it works fine, but in IE11, it sometimes doesn’t open the carousel but opens a single image. In Developer tools, the only bug found is:

    return f.advanced.updateOnSelectorChange&&(m=r(),m!==w)?(l(3),void(w=m)):(f.advanced.updateOnContentResize&&(p=[h.outerHeight(!1),h.outerWidth(!1),v.height(),v.width(),_()[0],_()[1]],(p[0]!==S[0]||p[1]!==S[1]||p[2]!==S[2]||p[3]!==S[3]||p[4]!==S[4]||p[5]!==S[5])&&(l(p[0]!==S[0]||p[1]!==S[1]),S=p)),f.advanced.updateOnImageLoad&&(g=n(),g!==b&&(h.find("img").each(function(){i(this)}),b=g)),void((f.advanced.updateOnSelectorChange||f.advanced.updateOnContentResize||f.advanced.updateOnImageLoad)&&o()
    Anonymous function [Line: 4, Col: 29276],

    jquery.mCustomScrollbar.concat.min.js

    Do you have any idea if this would affect the opening of the slider in IE11? The fancybox code and scroller code are in the same lightbox folder. I’m not a programmer, as you can probably gather!

    Hi Malihu,

    Your plugin looks really great! I’d love to use it, unfortunately I run into the issue trying to put a horizontal scroll. Here is my code:

    <head> <link rel="stylesheet" type="text/css" href="/global/scrollbar_plugin/jquery.mCustomScrollbar.css" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <script type="text/javascript" src="/global/scrollbar_plugin/jquery.mCustomScrollbar.concat.min.js"></script> <script> (function($){ $(window).load(function(){ $("#test").mCustomScrollbar({ axis: "x" }); }); })(jQuery); </script> </head> <body> <div id="test" class="mCustomScrollbar" data-mcs-theme="dark" style="width: 20%; height: 20%;"> ...some text... </div> </body>

    it makes a vertical scroll though. Checked on Firefox 31.6.0 and Chrome 43.0

    I’d really appreciate any help!

      Just found the solution. If you had the same problem, you could use the hack on window resize, which will make parent wrapper height to be the same as .mCSB_container

      The appearance and position of the scrollbar is set via CSS. Open jquery.mCustomScrollbar.css (it contains comments to help users).

      For vertical scrollbars go to line 65 and remove:
      right: 0;
      from .mCSB_scrollTools selector. This will place the scrollbar on the left of the content. You should also change the default margin(s) so go to line 54 and change:
      margin-right: 30px;
      to:
      margin-left: 30px;

      scrollTo is a plugin method, so it should be used after the scrollbar is initialized. For example:
      (function($){ $(window).load(function(){ $("#content-1").mCustomScrollbar({ /* options */ }); /* later on... */ $("#content-1").mCustomScrollbar("scrollTo","top"); }); })(jQuery);

          collapsible and active options are in the wrong place. They’re not supposed to be inside the mCustomScrollbar function!

          accordion function should be:
          $("#accordion").accordion({ collapsible: true, active: false, create:function(e,ui){ $(".ui-accordion-content").mCustomScrollbar({ setHeight:250, theme:"rounded-dark" }); } });

      If you experience issues with the published files, you might want to call mCustomScrollbar on window load (instead of document ready).

    If you need to update the scrollbars when you resize the browser, you can try this solution. It works fine!

    ( function ( $ ) { $(window).resize(function(){ //calculte height var disponible = $(".menulateral").innerHeight() - $(".pie").innerHeight() - 25; // destroy scrollbars $("#wrapper_menu").mCustomScrollbar("destroy"); // init scrollbars $("#wrapper_menu").mCustomScrollbar({ setHeight: disponible, scrollInertia: 0, setWidth: 210, theme:"bo" }); }); })( jQuery ); // init scrollbar ( function( $ ) { $( window ).ready(function() { var disponible = $(".menulateral").innerHeight() - $(".pie").innerHeight() - 25; $("#wrapper_menu").mCustomScrollbar({ setHeight: disponible, scrollInertia: 0, setWidth: 210, theme:"bo" }); }); } )( jQuery );

          It looks like a conflict between custom scrollbar and bx-slider. My guess is that you need to move:
          $('.rest-det').mCustomScrollbar({ ... });
          function (without the window load) after:
          $('.tab4-content').bxSlider({ ... });

          As it is now, bx-slider clones the last element without(?) the custom scrollbar, so you need to apply the scrollbars after bx-slider has done its thing.

    Hello,

    Thank you for this incredible plugin, have used this quite a bit. I was wondering, could not find a way to search through all the comments… just to read through specific queries & check if I am not re-posting a query that’s already posted.

    I had two doubts to check if I can get some heads up:

    1 – I am using a content scroller for 100% of page width, but not full height of the page height. Is there anyway I can use Mousewheel on the rest of the page, to initiate mousewheel for the scroller? Like scrolling the custom-content-scroller when user uses Mousewheel on the rest of the page body.

    2 – This same custom-content-scroller is using 100% page width, but is there a way out to center-align the content of the scroller? This is because at times I have lengthier content than the content-scroller width… but at times, I have lesser content than 100% of page width… in such case I wanted to have all the content (nested-div’s) to align in center.

    Any help in this regard will be appreciated. Cheers!!!

      Hello,

      1. I had made in the past such a test for vertical scrollbar (you can apply the same code for a horizontal one). I’ve uploaded it so you can see it here:
      http://manos.malihu.gr/repository/custom-scrollbar/demo/examples/trigger_mousewheel_via_other_elements_demo.html

      Check its source. It only requires a couple lines of code to bind and trigger the mousewheel event 😉

      2. This should normally be done via CSS (and probably few callbacks). I think I’ve done this at some point… let me dig my files and I’ll let you know.

        Hi,

        This is so cool 🙂 I just did saw the source.
        Writing my first reaction to THANK YOU… even before going for implementing the tweak in code.

        Cheers!!!

        Thank you, this just worked flawlessly. You saved my life here 🙂 since I was struggling before finally posting my question.

        Guess both the mousewheel speed/inertia is different, when using mousewheel on the scroller and when using the mousewheel outside the scroller (in my case it’s Window/Body). Probably because the Inertia is defined while initiating the scroller. But remains undefined when using mousewheel outside the scroller.

        For making the both even or somewhat simliar in scroll speeds, is there a way out to define the Inertia… when binding mousewheel event on #mousewheel-trigger?

        I did some reading here, a detailed approach:

          You could set a fixed pixels scrolling amount when initializing the scrollbar(s), by using the mouseWheel:scrollAmount option.
          For example:
          mouseWheel:{ scrollAmount: 60 }

            Hello,

            Just another clarification.

            Is there a way out to initiate (the scroll) the custom scroller on the page, based on mouse cursor movement towards left & right part of the page body? Kind of using the scroller on full page-width.

            If there are any examples on that, I’d love to refer the same.

            I referred to this http://jsfiddle.net/BYUdS/2/ but could not make the customscroller scroll based on that. Sorry for my poor coding skills.

            Cheers.

        Hello again,

        Absolutely appreciated, these two examples seems to be just exactly what I had in mind. Can’t wait to try these ideas to see how it works at my end.

        Will surely post my updates, after implementing these tricks.

        Best regards…

      I created a single page website and I am using a navigation to scroll to the different sections of the website. Now I would like to change the scrollbar to something similar to slimScroll. The problem is that when I add this plugin the scrollTo on the website does not seem to work. Can anyone help me out with this?

    Hi Malihu,

    Thanks for your great plugin.

    Do you experience any scroll issue on safari macos? Safari verison is 8.0.6 (10600.6.3). I tried your demo page. everything looks fine, but I am not able to scroll there by mouse and also can not drag scrollbar to scroll. It works on window safari.

      No I haven’t. I’ve just tested the plugin again on Yosemite/latest Safari with a standard mouse and Apple magic trackpad without any issues.
