When you decide you need to group certain products into a product class, you begin by creating this class.
To create a new product class:
1. In your store’s Admin area, go to the Classes & Attributes page (Catalog > Classes & Attributes).
2. Click the New product class button.
An editable field will appear on a new line in the list of product classes.
3. 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.
If necessary, you can edit the product class name or delete the product class altogether.
