I want to place to listboxes (drop-down with multi-select on) on a web page. I want to provide 2 buttons, "Add To List", "Remove From List". When the user clicks the "Add To List" button, I want the selected items in listbox1 to move over to listbox2. When they click on "Remove From List", I want the selected items in listbox2 to move back over to listbox1. Is this possible with JavaScript?

Any help or examples would be greatly appreciated.
