I have customised the navigation widget and the only ting I can't seem to do is change the grey box behind the responsive icon in the menu state when the responsive nav is visible.
On my site this is in use in two locations, on mobile for the main nav and all screen sizes for a second level nav drop down:
The image above illustrates the nav open on desktop screen width. I would like to be able to colour the icon and the background in this particular state but cannot find the the setting.
I can change the background colour when it is in the normal rest state from gray to transparent, but cannot find any reference to it being coloured gray in any other setting that might effect this "open" state. Also the grey is not visible when I hover over the box on mobile layouts and I cannot find the difference between them and the wider screen.
I am sure this must be a setting somewhere that I am overlooking... but just cant find it!
Any help would be appreciated:
