The first image shows the top menu section of the main page, and the second image shows the drop menu that appears when you hover over it. Based on Wix Studio, if you hover over the menu section in this way, is it possible to display the entire bottom menu and change the background color?
The short answer is - yes!
The longer answer is I’m not sure this is possible without a little CSS. I think you might need to target that when the menu is active/hovered, then you apply a custom CSS class that fills in the background color of the header
