Hi @trakill,
That sounds like a good idea. However, Workfront’s API does not currently support modifying form field visibility in real time or changing a dropdown’s available options after the form has been rendered to the user.
You can use the API to update the entire custom form’s dropdown list options via POPT (Parameter Options) updates, but this would affect all users and is not typically recommended for real-time booking logic as it could pose issues if 2 users rendered the form or booked the same slot at the same time.
