What do you call this interface control.
You have 2 lists, one of the lists acts as your pool and the other as your current values. Tends to look like this
[1 ] [1 ] [2 ] Add>> [2 ] [3 ] Add All>> [ ] [4 ] <Remove [ ] [5 ] <<Remove All [ ] [6 ] [ ]
The source list does not change regardless of the operations.
Thank you very much.
