It would be awesome to be able to enter lookup values that can then be used for values in dropdown lists. For example, maybe create a database table with 4 columns (lookupname, value, text, sortorder). Have a way to enter the values...example records:
cities, atl, Atlanta, 1
cities, clt, Charlotte, 2
cities, dc, Washington DC, 3
states, ga, Georgia, 2
states, fl, Florida, 1
Then have a way to set the dropdown to use one of the lookup values (cities or states in the example above).
This way you could reuse lookup values without have to add them to every dropdown and modify multiple dropdown values if any values change.
