Creating groups allows you to group tickets by type, date, or category. Once a group is created here you may click on Advanced Settings of a ticket to apply the ticket to the newly created group.
Click on Group Options on the top right of the ticket creation.
Next click create group. Name your group and add a sort order to have the tickets listed on the event page correctly.
Apply tickets to your newly created group in the advanced ticket setting in the ticket setup or edit.
Groups can help you create complicated seating charts and make sure rows and tables are not over sold!
This is how it will look on the event page.
