Custom fields visibility
Custom visibility rules can be configured for listings and profiles custom fields. The visibility setting allows administrators to control whether or not a field is displayed on the frontend.
By default, there are 2 options available: "visible" and "hidden".
When hidden is enabled, the field will not be visible onto the frontend but it's data can still be collected through the forms. This is particularly useful if you wish to create some kind of private data that should only be visible to administrators.
