A choice group is a set to pick from, with rules about how many the customer takes. Size, protein, toppings. Build it once in the Library and attach it to as many products as you like.
For a single priced add-on rather than a set, you want an option instead.
Creating one
From Back Office, open Menu Library → Choice Groups and select +.
From the POS: Menubook → Choice Groups → +.
- Name — at least two characters. Staff and customers both see it.
- Type — Select or Quantity. This is the one that matters; see below.
- Number of selections required — a minimum and a maximum. Minimum 0 makes the group optional; 1 or more makes it required, and the customer can't finish the item without choosing.
- Choices — at least one. Each has a name and a price, and can carry an Image, a kitchen alias, names in other languages, and its own alternative prices.
Then Assign to products to attach it.
Select or Quantity — get this right
The most common setup mistake is picking Select where you meant Quantity.
Select lets the customer take each choice at most once. Right for size — nobody wants two smalls.
Quantity lets them take several of the same one. Right for extra shots, extra sauce, extra bacon. With Select, they can ask for it exactly once and no more.
The minimum and maximum count total quantity, including repeats — so a Quantity group with a maximum of 3 allows three of one choice, not three different ones.
Pictures on choices
Set an Image on a choice and customers see it beside the name while they customise the item, on the kiosk and on your online store. They come from the same library as your product pictures — see Menu images.
Do a whole group at a time. As soon as one choice in a group has a picture, every choice in that group makes room for one, and the ones you've left show their first couple of letters instead.
A free allowance
A choice group can give a number of choices at no charge before it starts charging — two toppings included, extras priced.
The allowance belongs to the group as a whole, not to any one choice, so the customer can mix and match up to the limit. When a group-level allowance is set, it takes precedence over the individual choice prices.
On the POS, you set this in Menubook with Free up to: a Free quantity, and a Price per extra, which each choice past it costs. While Free up to is on, the choices' own prices are ignored — extras all cost the Price per extra. The POS says so in a note above the group's choices, and under the price when you edit a choice.
Keep them small
Four or five choice groups on a single product is about the ceiling before ordering it becomes a chore. If you're past that, the item probably wants splitting into two products.
Hiding a group from a channel
A choice group can be hidden on some of your customer channels and kept on the others. See Hiding a product from a sales channel.
