Modifiers

A modifier group is a question about an item. A modifier is one possible answer.

Item:            Cheeseburger
Modifier group:  How would you like it cooked?   (required, pick exactly 1)
  Modifiers:     Rare / Medium rare / Medium / Well done
Modifier group:  Add ons                         (optional, pick up to 3)
  Modifiers:     Bacon +$2 / Avocado +$2 / Extra patty +$5

Required vs optional

Required groups block the item from being added until they are answered. Use them only where the kitchen genuinely cannot proceed without the answer — every required group is a tap a server makes on every single order.

Optional groups can be skipped.

Selection limits

Each group has a minimum and a maximum number of selections:

Min	Max	Behaves as
1	1	Pick exactly one — a radio button
0	1	Pick at most one
0	3	Pick up to three
2	2	Pick exactly two — e.g. "choose two sides"

Modifiers and price

A modifier can add to the item's price, subtract from it, or leave it alone. Prices are applied on top of whatever the item resolved to along its path — so a +$2 bacon modifier is +$2 whether the burger came out at $14 or $8.

Modifiers and the kitchen

Modifiers print on the chit under their item. Keep modifier names short — they are read at speed, on a small ticket, by someone holding a pan.

Shared modifier groups

A modifier group can be attached to many items. Editing it once changes it everywhere it is attached, which is usually what you want — and occasionally very much not. Before editing a shared group, check what else uses it.

Where modifiers are offered

A modifier group can be switched off for a channel — available on the till but not online, for instance. See Channel visibility; this is a common source of "why was the guest charged for something the website never showed".
