Event Dependencies
You might have an event which depends on other events. That mean users need to register for other events first before they are allowed to register for the main event. That could be handled using Events Booking - Event Dependencies plugin
- Login to back-end of your site as a super admin account.
- Go to Extensions -> Plugins, find and enable the Events Booking - Event Dependencies plugin.
- Now, when you add/edit an event, you will see a new tab called Dependency Events. Enter IDs of the events you want there (comma separated) and users need to register for these events before they can register for the main event
