Question

1C-Bitrix

Guys, tell me how to display related products in the basket that have already been selected for purchase?
That is:
There is a product, additional products have already been selected for this product and put in the basket.

Now it should be output like this.
But this is layout, not dynamic data.
If I display the product itself and its characteristics in an array like this: But I can’t figure out how to display additional equipment for the product.CCatalogProduct::GetByID($arItem["PRODUCT_ID"]);

In what?
The first screenshot is a detailed product card, and the second is "checkout" or is it a shopping cart?
Did you write the component yourself or did you customize the standard one? How do you add " Additional equipment " to the shopping cart? (show code)
