jQuery: Clicking on grandchild hides everything

In the example below, I would like for root and current and child objects to be displayed when an item is clicked on.

The only problem is that this only works two levels deep.  For example, if I click on "Fruit" everything is hidden.  If you test this example you will see the problem.

Thanks.

use parents instead of parent to exclude all ancestors of the clicked node:
$('ul').not(  $(this).parents()  ).not(  $(this).find('ul')  ).slideUp(200);
