Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.Checking off Unique under Form Validation on an element (like name or email) can restrict duplicate registration to an event such as one provided through "Demo: Event Registration" but prevents registration for "Demo: Event 2" after registering for "Demo: Event 1".
While there appears to be a way to limit the "Per user submission limit per source entity" that prevents one computer from being used to complete multiple registrations whether the same or different.
The GUI configuration should allow limit only one Unique element (like Email) to register per webform as well as per source entity.
