Nested Category Layout will show a “nested” version of your product archives. This can be used on the shop page and / or any category archives.
If enabled for a page / archive, the products will be grouped together based on category / subcategory. In this example, Nested Category Layout is being used to show all products in our “Nested Category Layout” category, grouped by products with no subscategory, then by the sub-categories Clothing and Music.
You can also view this on the shop page to see all product categories.
