I think I know what you mean, it’s a parent/child relationship between fields in the same model.
So if you take the example of cars with two fields (Make/model)
If you select the make as “Ford” the models should only populate with models that are made by “Ford” like “Mustang” / “F150” / ect. Given I’m using a relational example here, but your point is dynamically adjusting the view based on other values. Given an enum and someone selects an “other” option a new text field should appear to fill out the information.
We don’t have an option for this yet, but it has been requested before.
