List categories inside a category map
I have made a lot of category maps to bring some order to the thousands of products on my site. But now when some one clicks the category they have no way to specify a certain type of product in that category map.
How can I list the contents of a category map above the enormous list of products in lets say two or 3 columns or even just comma seperated, so that people can click a sub category to more specify the products they are looking for.
A good alternative would also be if possible to display the categories that are inside the category map under the category dropdown menu in the sidebar widget.
Per example in the category map Telecom 20 other categories (everything from mobile phones to headphones and accessories) can be found: http://www.example.nl/categorie/Telecom/
So how would I alow a visitor to better specify what he is looking for?
I hope you can suggest something.
