Menu styling

I want to restyle the mobile menu on the Simplicity template but can't find the relevant CSS. Can someone please point me in the right direction? The Simplicity menu looks ugly (on iOS at least) and requires the user to make a selection from the pull-down menu then select done (two taps). I'd like to replace it with something like the Box mobile menu which looks much neater and goes to the selected page on a single tap of the menu item.

Hi

I'm afraid mobile menu is using a dropdown html element and the look of it depends how mobile browser presents a dropdown selection. You would need to remove the template menu entirely and replace it with other. I'm afraid this will require a massive changes to template. Too big to be supported by forum support, sorry.
