Product with variants

Hello,

I'm new to opencart

My problem is the following - how can I add a product with different variants. Each option should have a separate picture and description.

I want to get the same view as this url address:

https://aquasport-n.com/index.php?route ... ct_id=2547


Thanks in advance!

There are extensions that do this:
