On submission, PRO validates the definitions and submitted values. Required fields must be completed. For selection fields, only values that belong to the stored options are accepted.

The values are stored with the field label and field type on the registration record. In the participant list, they can be opened via Additional details. PRO also adds the data to the CSV export.

Labels, placeholders, help texts and options are additionally registered for dynamic translation via WPML/Polylang.
