If I sell out of a ticket type, I can close registration, but that just does not allow the ticket to be sold anymore. Is there a way to make that ticket type no longer visible.
If you want to make a event ticket type hidden, you can add a promo code to it. You can do this by going to step 6. Configure ticket types, then editing the ticket and adding a promo code. Adding a promo code will hide the tickets from anyone who has not entered the promo code in their url.
