Enable / Disable Form Types

It's possible to enable or disable specific form types.

Enable specific Elements

Only the hidden Element is available.

form_builder:
    admin:
        active_elements:
            fields:
                - 'hidden'

Disable specific Elements

All Fields except the hidden Element are available.

form_builder:
    admin:
        inactive_elements:
            fields:
                - 'hidden'

Note: If you're using both config elements at the same time, no field will show up (assuming that you're using the example from above)

Extended Type Configuration
