Displaying child categories

So editting my post, basically I was able to get the parent category to display the child categories, so that works now.

Now I would like to know how to display the child categories of a child category. For example take a look here: http://demo.nopcommerce.com/electronics imagine the cell phones category had two child categories like dumb phones and smart phones. How would I get this page to display the child categories as well? I would probably format this so that it would be under the child categories, but how do I get the child categories of the child category to display in the first place?

Thanks!
