We do something similar with a drop-down box and a text box. We make the
first item in the drop-down box "New Item" and if that is selected then we
look in the text box and add it (or ignore it if it is in the list, or raise
an error if it is empty). If they select an entry in the drop-down AND
enter something in the text box, then we ignore the text box. Not as
elegant as the solutions in other languages, but it works.

Greetings to all from down under (Australia that is!)
Just wondering if I could pose a question.
I am building a system and the client wants a few entry fields where
they
can behave like a list
box (ie: with a set of options loaded from a database table) but if the
option they want is not
there they can type it in and the system will add it to the database
table
for next time.
A few questions are :
1. Can you make a list box behave this way? I'm sure I've seen web
sites
with list boxes that
also allow you to type characters into the box. They could I use
an
event to test for a new
value or something.
2. Another option I guess is to use a normal text field and when they
enter
something I can
check to see if it exists and complete the field for them.
I am sure that CF allows you to do something suitably clever here - I
just
cant find it!
Any bright ideas appreciated.
