I have a P&T Dropdown that has a default value of " : Select one..." and once you select and submit any other option than that default... there seems to be no way to reset that fields value back to the default.
Consider I have Field#1 "Are you Coming?" and the another Field#2 "What you eating?". When I use selects Field#1=Yes then they get to submit field#2 as "Fish". However, they may later come back and resubmit as Field#1=No in which case I reset Field#2 (via JS) to " : Select one..." and set it to "disabled" and submit. This however does not reset the field.
