Prevent Uniqe Text in jQuery Autocomplete

Question

I'm working on a project where I need a jQuery auto-complete for Cities. What I don't want is for someone to enter in a unique city name and have it ball up my system.

I need to be able to CLEAR the input if someone types it in incorrectly and FORCE them to use the list I give them.

I can get the dropdown working properly using the jQuery AutoComplete, but I just cant figure out how to customize it for preventing invalid data from being inserted.

Answer 1

after searching the forums, I found a link to the options page where there is a mustMatch parameter. This looks like it might be what I'm looking for, so I'll give it a try.
