The above example illustrates the possibility of the dropdown list containing additional information-only columns, in this case the zip codes. It also illustrates the possibility of making the dropdown list a different width than the field. (See the discussion of coldef for details.)

Hitting Enter at that point closes the list and puts the selected item into the field:
