How to close mobile menu when using Page scroll to id plugin
In order to auto-close an opened mobile menu when links that scroll the page are clicked, you’ll need to add some extra javascript in your page or theme template.
This issue is not a problem that comes from “Page scroll to id”, as the plugin has no control over the mobile menu a site is using. The same problem would happen even if you were using other similar plugins or no plugin at all (e.g. the page would “jump” but the mobile menu would still be opened). This issue comes from the fact that most mobile menu scripts do not auto-close the menu, when menu links are clicked, simply because most developers forget that a link might point to an anchor within the same page.
