Is it possible to control the colours of the text and background of a field controlled by a drop-down list?
Basically, if there's already a value in the field, I want that value to be invisible when the user activates the drop-down. I hoped to do this via the Inspector (white-on-white, or something similar), but that doesn't appear to be an option. I fear that it's an os-level thing, but any ideas would be most welcome.
(I know a pop-up wouldn't have this issue, but this is a very long value list, so I need to use a drop-dowen to save filling the screen with the pop-up.)
