  // this will expand the second sub-list, when the accordion is initialized:
  $j('#container1').accordion({initShow : ">li>ul:eq(1)"});
  // this will expand the sub-list with "class=current", when the accordion is initialized:
  $j('#container1').accordion({initShow : "ul.current"});

  $j('#container2').accordion({el: '.h', head: 'h4, h5', next: 'div'});
