[TYPO3-shop] problems with subcategories

[Ana Nava]

Hello,

I'm extending the tt_products extension. 

I have installed the mbi_products_categories and nsb_cat2menu extensions.

The products are organized  with multiple categories and subcategories.

In my page, I have a pluging for the categories (type: Categories:list
CODE:LISTCAT).

I'm using the Banana template's to view the list of categories.

My problem is that the categories are showed but the subcategories not.

Thanks in advanced and regards

Ana Nava
