The CategoryTree is a MediaWiki extension that provides a dynamic view: you can change how much you see of a category's structure as a tree. You can use it to show a category and its subcategories by putting the category name between category tree tags like this:
<categorytree>
Trees in religion
</categorytree>
The result is a category tree like the one shown to the right. Click on the triangles to expand and collapse the tree.
