Add-on modifier groups

Modifier groups let guests customize an add-on at checkout β€” for example, choosing a flavor, size, or topping. Navigate to Manage > Add Ons (top level) to manage modifier groups.

What are modifiers?

A modifier group is a set of options guests choose from when adding an item to their booking. For example, a "Birthday Cake" add-on might have a "Flavor" modifier group with options: Chocolate, Vanilla, Red Velvet.
