Show only users in a list that is not in another user list (To be able to add them to the other list))

Hi!

I have a list of users with a button to add them to another list. The problem is that i dont want the already added users to show in the original list (so i dont add them again).

Anyone have a idea of a solution for this?

If there is a relationship field then you can filter your original list based on the Current User not being in that relationship field.

Hard to say exactly without seeing your setup.

Thanks a lot!

Can you show me an example of that?
