When you decide you need to group certain products into a product class, first, you need to create this class.
To create a new product class:
In your store’s Admin area, go to the "Classes & Attributes" page (Catalog > Classes & Attributes).
Click the "New product class" button.
An editable field will appear on a new line in the list of product classes.
Use the new field to enter a name for the new product class.
4. Click Save changes. The newly created product class will be saved and added to the product class list.
After creating a product class, it's necessary to add attributes and then assign products to it.
If necessary, you can edit the product class name or delete the product class altogether.
