I'm trying to figure out if I can add two other options to the drop down date field. This is the field that is available from the object library. Client wants two other options - "TBD" and "-" for unknown. Is that even possible? I thought about creating my own drop down box, but I wasn't sure I could insert the calendar option in the list of drop down items. Really like the calendar popping up and trying to make it easy for the client.
If I can't, I will probably put in a "fill your own" option for the drop down menu.
