Product add-ons are additional items that you can offer with your products. These add-ons are displayed on the product page for the customer to choose from.
If you have a large number of add-ons, you can group them in add-on groups making it more readable and convenient to understand for your customers.
Please note that add-ons are created under groups. A product can have multiple add-on groups, and different products can have different combination of add-on groups.
For example, a laptop can be sell with different combination of computer accessories, an external keyboard, Hand Bag, Camera etc. from add-ons list. You just need to add these add-ons once for the first time on a product. For all other products, this add-ons list will be pre-populated and only price values will be required to be entered, hence making it convenient.
Enter Price and set Priority of add-ons by selecting the add-on group and click save.
