Is there anyway to use a controlled vocabulary with the contribution plugin? The way my group is using Omeka, we'd like contributors to provide all the metadata associated with an item, but there are some elements where we'd like them to be limited to a controlled vocabulary. I'm using Simple Vocab which works on the admin side, but is there anyway to force contributors to choose from a dropdown menu?
I'm also curious if there is anyway to make certain fields in the Contribution page required, so users cannot submit without entering something in those fields?
Thank you!
