Grouped product is a product type in WooCommerce that allows you to create a bundle of related products as a collection. These products can be different variations of the same product or entirely different products.
Grouped products consist of Parent and child products.
Parent product: Parent product, also known as base products, is the main product that will have more than one related child product.
Child product: Child products are related to the main product or parent product. There can be multiple child products for a single-parent product.
When a customer views the grouped product, they can either purchase the entire grouped product as a bundle or purchase individual child products.
For example:
Consider the above product bundle on Amazon. In this bundle, the GoPro Hero 12 is the parent product, and the accessories included, like the battery, head strap, carrying case, etc, are child products.
