Input field to autocomplete from existing things or create new thing

I’m looking for a way to have an input field for a list thing that when user starts typing will display matching results as well as allowing user to create a new entry in that list. Some context:

In my app Users are teachers. Another data type is Subject Areas (with options like Math, Biology, Chemistry, etc). The Subject Area field in Users is a list. I can use the Bubble multi dropdown plugin to permit app users to select from existing list of Subject Areas, which are displayed like so…

The problem is this input type doesn’t allow the creation of new Subject Areas; how to accomplish that?


Were you ever able to find a solution to this @jheuer?
