You can add modifiers to any of your menu items. Adding consistent tempting modifiers has been shown to increase the price of customer orders.
These can be anything: including sides to be added, things which affect the meal itself (“large” / “vegan”) and it also means that you can sell bundles on the product level (“big burger meal”) which can be altered via modifiers.
To add modifiers, go to the menu of your store, and click on an item. Then, click on modifiers in the top right of the pop up box.
Modifiers can be optional, required, mutually exclusive, or not. You can set as many categories as you like.
If a modifier is optional, set the minimum number of modifiers in that category to zero.
If a modifier is required (e.g. small, medium large) set the minimum number of modifiers in that category to one.
If modifiers in a single category are mutually exclusive, (e.g. small, medium, large) set the maximum number of modifiers in that category to one.
You can add as many categories as you like.
