Related products in product list

Hello, is it possible to display related products in the product list page as a complement of the product reader page ?

I guess it is possible by adding some code into the product list template but i don't know what code i should insert .

I guess it should start by something like this

Code:

---

if ($products->related){....}

---

thanks

That is not possible, because you would not know which product in a list you want to show it for. Do you want to shop related products to specific category?

Yes, i've set product list page for each category of products but i don't need a product reader page.
