I have an Acrobat 11 form with simple data entry fields. I have, for the first time inserted dropdowns and most of them are single-line fields. However, there are a few examples where my field has to be a larger size to obscure an unwanted background. (The field will set the background colur to white if data is input but I didn't write the script for that.) When a selection is made it appears centred in the field and I need to be alligned to the top.
You don't have any control over that. They will always be vertically centered. You can use a separate field underneath the dropdown, however, and control its background. I'd suggest using a read-only button.
George, thanks for that. I'll give it a go.
