value lists over 30 items long are a pain for the users.
I usually build a popover control or layout that allows search and selection of the values.
Search for related value lists as this concept may be useful.
You could use a filtered portal. When you select the value in the first drop down you could then see all sub items in the filtered portal. If you needed to get really fancy you could use the first 2 selected to filter a third list.
Thanks to everyone for your help. I realize I may have over estimated my learning. Anyway it gives me something to work on.
I can see the potential in the Magic Value List link that Mike posted. I downloaded the file and looks to be very close to what I think is possible for me at this point.
Again thanks for your help.
