If your referring to the outside of the quicksearch menu, adding the following in EXTRA or maybe go into Style Properties, in the menus might remove it if it's available there. If not, paste the following in EXTRA
Code:
#QuickSearch.active { box-shadow: 5px 5px 25px rgba(0, 0, 0, 0);}
Is there a way to just change the search texts only? not every form pop up texts? The code you gave me worked, but it made all other form containers texts go black as well. Is there a way around this?
