Drupal Commerce 2.0 Line Item


I’m trying to set up an ecommerce site using Commerce 2.0 For Drupal 8. Here’s a briefly description of the expected behaviour.

A product can have multiple atributes which obviously will make the price different. But in my case there are some Atributes like SIZE or COLOR that have no impact on the product’s price. (Product’s price is the same if ordering a red, blue or green one)

How can i define those 2 attributes in a way like a Line Item (from the previous version – Commerce 1.0) in order to avoid generating thousants of product variations for nothing?

Thanks in advance & regards !
