In my application I have 2 objects. An Item object and SubItem object.
What I would like to do is make a single drop down list that has all of
the Items in it, then if the item has a SubItem attached to it, then it
will be displayed directly underneath that Item with some sort of
indentation or marking to indicate that it is a SubItem. I don’t even
know where to begin looking for this type of problem. Any ideas?
