It's really the nested ul you want to be showing, when you click the parent li, so your click handler was wrong, slightly. I also updated some styles to get this to work a little better.

$(document).ready(function(){
   $('#categories li').click(function() {
      $(this).find('ul').toggleClass('selected'); 
   });
});
