Limit Number of Characters in Dropdown List

In my dropdown list, I selected the option "Allow user to enter custom text". The problem is that the user can enter an infinite about of text and I'd like to limit the number of characters so that text longer than the visible area can't scroll. There are no options that will allow me to do this in a dropdown list like there are in a text box. Is there a script that I can add to my dropdown list?

You can use this code as the field's custom Keystroke script to limit it to 10 characters:

event.rc = AFMergeChange(event).length<=10;

The code will probably disappear after you enter it. That's OK. It's still there and should work.

This worked. Thank you! Especially for the disclaimer about the code disappearing. It did disappear but still worked. That would have confused me.

A tip for anyone else has the same problem: Make sure that the character limit is equal to or greater than the number of characters of your longest option in your dropdown so that you don't accidentally block the user from being able to select any options.
