Question

1C-Bitrix

Good afternoon! The site has an interesting output of the product when you go through it. category opens. How to implement something like this? You need to do the same with this site.

Answer 1

On the first link on the site, when you go to the "product" in fact, either a section opens again, or an info block element that is not a product catalog. In the first case, real products are linked to this product section, and in the second, real products are linked to the info block element . But it still seems to me that this is just another section, because. The page says it's a collection.
Alternatively, you can dodge and create collections through the HL directory and link products to its elements.
