I need a dropdown box which get's the values out of another table. In the 1st field there should be the primary key (UUID) of that records, and in the 2nd field there should be a text field. The 2nd field is the only which should be seen. That's all no problem and worked fine. My Problem now is, that the 2nd field should be a concatenated string of 2 fields out of the records, but I can only select an atomar field of the related table. How can I do this?
Thanks for help
