How to make an extended product card?

Question

1C-Bitrix

Good afternoon.
We have 2 sites: norms and finalized .
The bottom line is that it's normal. the site has 4 sizes and colors, and if you choose white, it displays only those sizes that are in this color and so on ... and the warehouses where the products are stored are different ... how to do this? otherwise my prices went for 1 product, but different colors - a different amount, etc.
How is an extended card made? Is it a module or is everything done in standard Bitrix?

Answer 1

In Bitrix online stores, this is called a product with trade offers.
You need to create them))
Tell us what type of license you have, Bitrix has a lot of different stores...
