    Filter out used values in a popup


      I am trying to filter a popup menu so that any time I use a value it no longer appears in the menu.

      So I have Events at a Venue which has seats , so when someone attends an event I want to assign the person a seat.

      I can populate the dropdown menu with a list of seats which is great but i don't want the user to be able to pick a seat that is already taken.

      the assigned seat values are stored in the EventManger


      how can i filter this list based on their use in EventManager ?
