I wrote a little jQuery script for accordion menus. Hope you like it:

First, create your HTML markup as follows:

<div id="sel">
  <h4>title 1</h4><div>content 1</div>
  <h4>title 2</h4><div>content 2</div>
</div>

Then add this to your javascript:

/* jeff's tiny accordian */
var aMenu = function( sel ) {
  $(sel+' div').hide();
  $(sel+' h4').click(aMenuClick);
}
var aMenuClick = function() {
  $(this).next('div').slideToggle(500).siblings('div').slideUp(500);
  return $(this).next('div').length > 0 ? false : true;
}
$(window).bind( 'load', function() { aMenu( 'div#sel' ); } );
