I'm trying to make a few custom tag fields with MC12. I'd like for them to be lists that I can choose multiple entries from for any given song. For example I'd like a sub-genre tag that I can fill with the tags 'Folk' and 'Acoustic' (along with other possible values). When I select a song and edit the tags, if I choose both Folk and Acoustic the sub-genre field just resets to empty (rather than have a field that displays "Folk;Acoustic" or something similar).
How do I set up my custom library field to do this?
It seems like it should be possible since the Keywords library field behaves the way I'd like my custom fields to behave. I can't figure out how to get it to work though. My library field is set up for Audio, User Data, List (semi-colon delimited), Standard Edit type, a long list of values, with the "store in flags" option checked. This appears the same as the keywords, aside from the search portion.
Help is greatly appreciated,
JB
