I would also love this feature! I am creating a database for local food options for our office.
I need people to be able to choose from an existing restaurant list or add a new one. If they add a new one, then more fields should appear to add details of location, whether you can sit in etc.
At the minute I’m considering embedding two separate forms on the same webpage - add venue in one or add food in the other. But it’s really clunky!
Suggestions or workarounds welcome. I was looking at using other form services that integrate with airtable but I really like the ability to upload images in the native form.
