What's causing my search bar and menu navigation overlap issue?

Hello,

I have an issue on my store where clicking on the search icon opens up the search menu from the header, but the menu navigation is still visible. I’m using the Dawn theme and I also have Cloud Search and Product Filter but I doubt the latter is the one causing issues. Also using Qikify too.

Was thinking about adding an always-visible search bar but I doubt that’ll fix the problem, I have to get through this first. Site is dewyglowskin.com

You can try go to the base.css file, find the class details[open]>.search-modal and add a new property

z-index: 999

This worked, thanks.
