Trying to create a very simply Sign-Up form. I have two fields: Name (text field) and Select Date (choice field)
I would like to have the Select Date dropdown only show available dates remaining.
Example: There are three dates available to select:
Person 1 has selected 5/1/2023. I would like to have the option of 5/1/2023 removed from the Select Date dropdown for any subsequent user filling out the form. How can I filter out already selected dates? Thank you!!!
