I need to allow multiple registrations ie that a person can register multiple participants in an event. It is necessary that this person can edit certain entries to change or cancel them.
In backend I want to easily find the list of participants with the last modification date or the cancellation date. Is this possible with your component? Can we sort the list of participants in an event by date modified?
You can use Group registration option to register for several registrants. You can also edit information of these registrants. However, when you cancel the registration, the registration for all registrants in this group registration will be cancelled.
You can see all registrants from back-end, sort them by register date but not modified date (the extension doesn't track the modify date of registrations records).
