You can easily archive events you are no longer using. This effectively hides the event from all students but allows you to make it active again at a later date.
To archive an event, select the Training Admin Workspace. Under Manage Training on the left, select either In-Class or Virtual Events. Then select the event from the list.
On the right, select Archive.
Please note that when it comes to bundle events, if you archive the master event then all the other offers will be archived as well.
Archived events can be found by filtering the list of events by Archived status.
