I want to implement a paring system using list and jquery.

 Excel Fields DB Fields Mapping email name email+emailId address emailId >> empId+empcode name empcode (ADD PAIR) empId address << (REMOVE PAIR)

In the above example when I select items from both(Excel Fields,DB Fields) list and click ADD PAIR it should show the pair under Mapping list and the corresponding items should be removed from respective list. When I select a item from Mapping list and click Remove pair it should remove the item from mapping list and add the individual items to the respective list. My question is there any jquery plugin to implement this.OR any example available on web which shows how this is done. Thanks in advance!
