The fields all appear to be of the same length. Couldn't you simply make the text fields wider and higher? Maybe I'm missing something here and I don't mean to be obvious.
I think Edison Hu wants to specify a narrower field size and see the text from the value list "wrap" to a second line--presumably indented to align with the left edge of where the value list text begins in the previous line of text.
That would be a very nice new feature for FileMaker, but not something that is within current capabilities for a Single field formatted with radio buttons.
