all the google results and youtube searches did not give me an answer. I hope the WP mothership can.

I am building a small shop (im an artist, few products 3 categories, 1 sublevel) The shop page (woocommerce) works well but displays all categories. I want the website to be a portfolio-shop, therefore have the various media I use in the menu itself.

One of the Menu Items is called Portfolio. When clicking, you see 1) drawings 2)oil paintings 3)sculpture. But each of them has a subcategory. I made all the products pages, they're fine. Ex of subcategories: Drawings have 1)graphite, 2)slates and 3) 18+subjects.

QUESTION: how can I make a page or change the general drawings page I made to show only /product-category/graphite? I tried to change the page url itself but it doesn't take the slash / it simply jumps to /product-category-graphite which, will return a 404 Thanks
