I would like to create a webform with a select list/radios where each option on the list can be chosen only once (unique). I can of course check "Unique" in Validation settings but this is not an optimal solution because users have to "guess" what values are still accessible.

Is there a possibility to create a webform field where:

  • the field is required (select list/radios),
  • each value can be checked only once (unique),
  • checked/chosen values are hidden/disabled if they have been used once by other users.
