The categories module has to be added to other modules. Download the catalgue module, you will a Breadcrumb in each product, that show the relation between the mother and the child.
This breadcrumb depends of the catalogue modulo, not the categories module. You have to add this function to your news module. I decided to put a Breadcrumb but you can use any other design.
The function leveltemplate, line 162 of datatypes/category.php, orden the categories. The catalogue module call this function (lines 53 and 108 view_category.php, lines 92 and 108 class.php of catalogue module) and send it yo smarty.
In the case of the product. It only get his parents to create the breadcrumb (lines 47-54 and 84 view_product.php) and send it to the smarty.
In the tpl you can do anything.
You can see it in action in one of my clientes, the design is very bad (we aren't the designers), but the catalogue works fine. Click here.
