Let's say you have a trip planning app where your users can fill out a form to create a new trip. You may want to have the user select a Trip Category via a dropdown so they have to pick "Adventure," "Leisure," or "Educational."
-
To do this you need to make both a Trips collection and a Trip Categories collection.
-
On the Trip collection, add properties for Name, Image, and User.
-
Then, on the Trips collection, add a relationship property so that each Trip can be related to one Trip Category. Name the relationship property "Category"
-
In the Trip Categories collection, add a Name Property.
-
Then add Trip Category records for "Adventure," "Leisure," and "Educational"
-
Now, add a new screen to your app
-
Select the "Form" screen template
-
Select the Form
-
In the left panel, set the form to Create Trip
-
Now, expand the Fields section
-
Add the "Category" property to the Form Fields section

That's it! The Category field will automatically be a dropdown field on your form with "Adventure," "Leisure," and "Educational" as the three options.
