Sorry, don't get it. You want to have a separate view for each level? If not 
and you want to have something like the file explorer in windows with its 
directory tree, we are are alreday there. Because to me it looks like Whisker 
is exactly doing this:

Foo
 |--- Bar
 |       |--- A
 |       |      |---  the classes in category A
 |       |--- B
 |              |---  the classes in category B
 |--- Baz
 |       |--- the classes in category Baz
