Hey so I've added a custom liquid under my heading and when I click the sidebar menu on mobile mode the overlays in my custom liquid overlap the menu page. I can’t figure out how to make the overlays disappear. Is this something that I can edit in my custom liquid or something I have to edit in json?

Thanks for the reply, fortunately I just figured out the solution from my friend JonasS. Changing all the z-index values to 0 fixed the problem.

Hi Studdywear.

You can try to change z-index value of `.overlaybutton a`  to solve the issue

Omg thank you! I had no idea of doing that, I changed all of them to 0 and it worked!
