What an add-on group is
An add-on group bundles related add-ons with a selection rule. For example, a "Drink" group with Coffee, Tea and Water — the customer can pick one, optionally pick one (with a "None" choice), or pick multiple, depending on the rule you set.
Selection modes
Three selection modes are available:
- Single — customer must pick exactly one. No "None" option.
- Single (Optional) — customer can pick one or skip. A "None" entry is added.
- Multiple — customer can pick zero or many.
Scope is either Per booking (charged once) or Per person (charged per attendee).
How to create a group
- Go to Admin → Appointments → Add-ons → Groups → New.
- Pick the selection mode (Single / Single Optional / Multiple).
- Pick the scope (Per booking / Per person).
- Select which add-ons belong to this group.

- Save.
