Use this article to attach modifier groups to a product from the Product Modifiers card on the product form and set their display order. Once a modifier group exists (see Creating a modifier group), attach it to each product that should offer those choices.
1. Where is the Product Modifiers card?
The Product Modifiers card is on the product form: edit the product and scroll down the right-hand column to Product Modifiers. Click the Select modifier groups picker on that card.
2. How do I pick the modifier group?
To pick a modifier group, start typing the group name in the picker and click the group in the list. You can add several groups to the same product.
Selected groups appear as chips in the picker. A Display order list appears underneath; use its up and down arrows to control the order in which groups are shown online and on the POS (first in the list shows first).
3. How do I save and check the product online?
To save the modifier groups on the product, click Update Product. On the online store, the product page now shows the group under its external name with each item and any extra charge.
Tip: The "0/1 selected" counter on the store comes from the modifier group's minimum and maximum selection settings.
