Once an event date has passed, or if you need to cancel an event, you can archive events, which will remove them from your list on the Admin page.
From the Events page, select Event Details to be taken to the event itself.
If the event date is in the past, you can archive the event from the Events page by selecting Archive Event.
From the Settings tab, choose Archive Event.
Confirm the choice to archive the event.
Once you archive the event, you'll see the title change to (archived), and you'll have the option to immediately unarchive the event.
You can also unarchive any events from the main Events page.
Select Archived Events from the Categories dropdown to see a list of events you've previously archived.
Enter the name of your event in the search bar then choose Unarchive Event.
Confirm you want to unarchive it, which will remove it from the Archived Events category and put it back on your events page.
Your event will be moved to the main Events page, so you can access it from there.
