Following this thread, I have been able to customize my dropdown menus as I desired.
However, there is one last thing I haven’t been able to customize, which only happens when the dropdown is focused (see picture below):
There is this weird white box appearing in the select control area that appears when I focus the dropdown menu. After selecting an option, it disappears, but reappears if I refocus on this dropdown.
Do you know which property I should edit to get rid of this behavior?
Edit: only happens if searchable is False.
