I’m currently trying to integrate a Stay-on-Top Feature for the Mobile Menu, but I have some Problems with the CSS Code. So currently I’m using this Code for #masthead:
Which results in a very ugly Problem: The Menu stays on Top, but if you open all Sub-Menus you can’t scroll through the Menu, because the Website behind is still scrolling. Also if you extend a new Item in the Menu the Content on the Website scrolls down.
