If you have a TreeView that shows categories - yes. You can put it that way.

Others would call them nodes, and nodes that hang at the line under the 
same node (their parent node) are its children. In most cases, children 
appear indented to the right in a TreeView. The node above which is not 
indented or one step less indented is their parent.
