Checkbox Type

• Use Checkbox Type if you want to offer users ability to create a product bundle by Selecting one or more items from the Add-On list and Only add the selected Add-Ons to the cart when the main product is added to the cart.

• As Shopify offers various different Cart types like Ajax Cart, Cart Drawer (Shopping Cart which opens up a drawer from the right hand side) or Form based cart, Upsell Product Add-On app works out approrpiate cart in use and adds the Add-on correctly to the cart. However some themes might not work with Checkbox Option, in that case please contact support and we can configure the app appropriately for your theme.
