Taxonomy hierarchy based classified ads

Hi there,

I would like to create a classified ads page that would display all taxonomy categories related to the ads. I'm using ed-classified module + views bonus pack. I've created a vocabulary for this content type, looks something like this:

First category
--subcat1
--subcat2
Second category
--subcat1
--subcat2
and so on...

Using lineage with arguments I'm only able to display anything if I create a new content into a specified category, for example "First category / subcat2" only showing up if there is content posted into that category. When views is disabled I'm able to see the general ed-classified layout with the main categories and then a link to subcategories but that's not what I'm after. My question is, is there any way to get all categories with parents and children displayed even if there is no content posted into them? I've tried to use views, add field Taxonomy: Terms for Classified - nothing came up.

Any help would be greatly appreciated.
