In the backend i see that all registrants have an ID. This # is not present in CSV export, is this possible?
Also is this ID unique to one event? So that registrants for another event can get ID #1
Right now, the ID is not available in the export. It is unique. If you want it to be available in csv, you can edit the code in the file administrator/components/com_eventbooking/controller.php, look at csv_export function .
