Creating a custom products page based on new filters in prestashop 1.7 module

Question

I have preashop 1.7.2.4 installed. I created a module with a controller and connected to the ModuleRoutes hook to create my own specific route that really works! :)

in general, I created a new set of secondary categories in my prestashop module, and I would like to create a product page that displays only matching products based on a category 2 set.

so I created a field on the first page that will search by sets of the 2nd category, and then redirected to the correct friendly URL, which is caught by the ModuleRoutes hook and correctly opens ... a blank page at the moment :)

How can I create a custom cart product page and all that? don't know how to move on from here.

All information regarding this issue would be greatly appreciated.

thanks
