I created a shopping cart with categories and products. But when puclishing the shop, I cannot see the categories "on front" . I mean it the usual shops, when you enterd at main page, you see the categories, them you choose a categorie, and here you find the products under the selected categorie. 

In my view, actually only show ALL the products, with the mention of the categoties as a information inside the detaisl of the products. 

Is thei correct?.

Thanks for the answer.
