Magento_GroupedProduct module provides ability to offer several standalone products for sale as a group on the same Product Detail page. It can offer variations of a product, or group them by season or theme to create a coordinated set. Products can be purchased separately or as a set. Each product purchased appears in the Shopping Cart as a separate item. This module extends the existing functionality of Magento_Catalog module by adding new product type.
