Calling another action from one action.

Question

Hi all,

 

I have a big one at least for me.

I have a product page that is listed by category, calling this page A

From page A when I click a product, I should be redirected to Page B where product family is listed, this page B is also directly accessible where you can from a list of product list the product family.

 

Page B is made of a page and partial page.

 

The problem is I dunno how to make page B show correctly, the page and the partial page when called from page A

 

I hope I get it correctly

 

Any help please
