On an asp page, I have a populated select box with an "add" button next to it. I want a user to be able to select an entry from the populated select box, and when they click "add", that entry will be entered in another "container" select box on the same asp page. I want them to be able to enter several items to the "container" select box in this way, one at a time.
Does anyone have any suggestions for this one?
