Question 1: Can I add a smart bundle, a grouped product, or a composite product as Bought Together items to another product in my store?
Answer: No. All products created by WPC Product Bundles, WPC Composite Products, or WPC Grouped Product plugin are special product types, which cannot be included in any other product type. It’s only possible to add simple, variable products or a variation as optional extra Bought Together items of another product.
In order to add obligatory/required extra products, you can use WPC Force Sells plugin. After installing these plugins, users can add items from the Bought Together tab or Force Sells tab.
