Hi, I’m having several issues with the menu and am unable to find a solution that works. I’ve searched through various threads and tried all the js snippets out there, but they don’t work for me. I’m using a fixed header/menu because that’s how I want to navigate (on a mobile device.) I don’t use any fancy 3rd party plugins (only duplicator + duplicate post) and am using latest versions of Wordpress + Theme X + Cornerstone.

To replicate the mentioned issue, please select: DIENSTEN, OVER ONS, or CONTACT from the menu, as they are page anchors. The other links navigate to other pages/sites.
The issues are:
1: The responsive/mobile menu doesn’t collapse on selecting an item from the menu
2: On Chrome for Android, the width of the menu changes when you select an item from the menu. (This cannot be replicated in emulation on chrome for desktop - screenshot attached from mobile device)
3: The responsive menu doesn’t work at all on safari for desktop (doesn’t open on click)
Lastly, the page can be zoomed out (as you can see in the screenshot about the changed width menu. This may be unrelated to the menu, but is undesirable anyway. I don’t want the page to be zoomable and would like to keep the width fixed to the viewport.
Below screenshots were made with an android phone (samsung), and have been confirmed by various users.
