Is it possible to format a ‘dropdown’ field so that the edges are squared off? If you look closely at the attached screenshot you can see that the edges of the ‘Filter by Type’ are rounded-off.
This is because you are defining each border independently. The roundness options are there “Top-left”, “Top-right” etc. If you unselect the independent option you will see it will say “roundness”.
100% sure as I’ve changed the style to not set the boarder independently and roundness to 0 in the image - I can see the full boarder and it still has a rounded corner.
I have also found that dropdown formatting and function options in general are limited (e.g. show an image or icon together with text). For this reason, whenever I have needed to do anything beyond the most basic of dropdowns I use a group as the initial UI element and then GroupFocus containing an RG for the options. Then you can implement whatever you want in terms of UI for both the initial element and what is shown on click of the dropdown.
Example 1: The GroupFocus contains an actual dropdown as well as a checkbox for filter.
Example 2: The GroupFocus contains a checkbox to limit the long list of results.
