   Flask-AppBuilder also runs validations for every field when it's submitted. I was not able to find a way to conditionally add/remove fields depending on the submitted `conn_type`, so that means that my PR alone would not work.
   
   However, it's possible for a provider to get it to work using a validator that's conditional on the `conn_type`:
   
   ```python
   class InputRequired(wtforms.validators.InputRequired):
       field_flags = ('required', )
   
       def __call__(self, form, field):
           conn_type = form.conn_type.data
           if conn_type == MyHook.conn_type:
               super().__call__(form, field)
   ```
