Hopefully a very simple question...
Is it possible to shade in the selection of a dropdown list whilst leaving the background white? e.g
For example how do I shade in just the "(All)" area but keep the backdrop white? I haven't been able to find this option under Format Filters.
I don't think you're able to do this because the formatting of the body of the filter applies to both the background of the filter and the actual content (dropdown in your case).
