Allow users to add to option set?

[esme_borisoff]

Hi everyone,
I have a user sign up page where they select their location from a dropdown menu. one option is “other” if their city is not in the list. I then have an input field next to it where they can add a city that is not in the list. However I’m stuck on how to then make this entry their city, so it displays the city entered instead of displaying “other” where it displays the city.

Photos attached! Thanks for your help

You have to use custom datatypes (Things) for that. This is one of the main differences between using Things and option sets.
