Timmie, I see a workaround in ColdFusion that is the following:
1/ SELECT statement, INPUT statement and some Javascript. Javascript function hides the INPUT in an appropriately wrapped DIV. 2/ In the SELECT include 'Other' as part of your OPTION list. 3/ If 'Other' is selected then the DIV/INPUT pair is displayed for the user to input a new item. Database update occurs. Not as elegant as a combo box but it works.
