Search and/or display sub categories of a category, etc.

[Curtney Jacobs]

Greetings!!   How do I search and/or display sub categories of a category? Each category may have zero or more subcategories   I have setup my relation in my application.xml file like the following:    <relation from="category" to="category" type="posrel" />     I know that I can use "relatednodes" to get the subcategories of a category, however, how do I get that subcategory's categories, and etc?   I know, I have been asking a lot of questions of late, bear with me. Your replies are greatly appreciated.   Curtney
