You could have a Private $aTags As New Variant[] in your class which associates a Variant with an item via the item's index. You need to maintain that array, though. Watch out for the Add(), Clear() and Remove() methods and the List property! I'm not familiar with the sources, so I don't know if there is a smarter way (and I'm assuming that you write the extended ComboBox in Gambas).
