Assign attribute groups and sets to a product

  1. In the WooCommerce admin backend open the edit product page
  2. Scroll down to the section 'Product data' and open there the 'Attributes' tab
  3. From the toolbar at the bottom you can choose to either add an attribute group or an attribute group set. After you selected an item click 'Add' -> All the assigned attributes will get added


Current limitation - Re-adding attribute groups on the product edit page. 

Adding an attribute group with an already deleted attribute (without saving in between) doesn’t re-add it at the moment. Simply reload the product edit page, re-add the desired attributes or groups again and you’re good to go.
