Before you start
Create and save the main event and the events you want to offer as add-ons. Configure tickets on each add-on event first. The selector uses the selected event’s first ticket and its price. Set that ticket’s inventory and per-order limits, and check the event/date capacity. For Shopify, follow the Shopify event add-on guide: every add-on must be published, with Hide Event from Event Listing enabled to make its Shopify product Unlisted.Configure add-ons

Enable Add-ons, choose the minimum and maximum selections, and decide whether overlapping time slots are allowed. A minimum of 0 makes add-ons optional.

Select the saved add-on event. Its first ticket supplies the price; configure the event’s privacy setting separately before publishing.
- Edit the saved main event and select Event Add-ons.
- Turn on Enable Add-ons.
- Set Minimum Required (0 means optional) and Maximum Allowed.
- Choose whether to enable Allow Time Conflicts. This permits overlapping add-on time slots, useful where different people attend different sessions or overlapping attendance is intentional.
- Click Add Event Add-on, then choose the saved event under Select Event.
- Review Addon Price and the first ticket’s name when shown. If the dialog only shows the event name and pricing note, open the add-on event’s Tickets step to verify the first ticket’s price before confirming Add.
- Check Configured Add-ons and save/update the main event to persist its configuration.
