Display all level categories in update product !

[ap3]

Hello,

I have organized my categories like this :

   - Home

      - Type

      - Mark

         - Mark 1

            - Model 1

            - Model 2

            - ....

         - Mark 2

         - ...

 

I have 3 levels and I would like Prestashop display all the sub sub categories when I create or update a product.

 

I have too to develop a custom search module using this system.

 

I have found productcategory module but I didn't find the way to display all levels depth.

 

How can I do ? 

 

Thanks in advance.
