We have a dropdown box on our form, and would like to enable the "Other" option to allow a user to enter a value not in the drop-down.
Alternatively, a 2nd dynamic field could be there to free-text other.
In either case, how can we configure an alert to warn the user of something BEFORE they are allowed to enter text in the field?
Say, the click to type free-text in the dropdown and Modal or Popup warns them "hey, you can do this, and we'll note it - but it is currently not a supported option - blah blah blah"
