Hye the community and first of all sorry for my english.
Here is my question.
I want to know if it's possible to do things like that :
Categorie1
Categorie 1-1
Categorie 1-2
Categorie 1-3
Categorie 2
Categorie 2-1
Categorie 2-2
...
Categorie 3
Categorie 4
...
When we click on Categorie 1-1, we see all the products of this category.
And when we click on Categorie 1 we see the link Categorie 1-1, Categorie 1-2 and Categorie 1-3.
Can we have a product list that contains the 3 categories when we click on Categorie 1 instead having the links ?
I haven't find solution so i wish your help could resolve it

Best regards
