There are two options of the product display, the same model group as on product page or each variant of the same model as individual page depending on how you wish to communicate your product to the buyers.

Option 1: one product page, regrouping all variants
Option 2: one product page per variant

Option 1: one product page, regrouping all variants

The same model can be assigned for different variants of one product. This groups the variants on the product page. You may find all the variants listed together on the product page.

Option 2: one product page per variant

Separate the products by variant, and each product sheet/variant will be displayed individually. This display allows the buyers to view all the variants when entering the category page.
