Multi Accordion with mootools problem

I created a mootools accordion with nested sections like this:

html:

<div class="accordion">
    <h2 class="accordion_toggler_1 open">Section 1</h2>
    <div class="sub_accordion accordion_content_1 open">
        <h2  class="accordion_toggler_2 open">Section 1.1</h2>
        <div class="sub_accordion accordion_content_2 open">
            Content 1.1
        </div>

        <h2  class="accordion_toggler_3">Section 1.2</h2>
        <div class="sub_accordion accordion_content_3">
            Content 1.2
        </div>
    </div>
    <h2 class="accordion_toggler_4">Section 2</h2>
    <div class="sub_accordion accordion_content_4">
        <h2 class="accordion_toggler_5">Section 2.1</h2>
        <div class="sub_accordion accordion_content_5">
            Content 2.1
        </div>
        <h2 class="accordion_toggler_6">Section 2.2</h2>
        <div class="sub_accordion accordion_content_6">
            Content 2.2
        </div>
    </div>
    <h2 class="accordion_toggler_7">Section 3</h2>
    <div class="sub_accordion accordion_content_7">
        Content 3
    </div>
</div>

JS:

window.addEvent('domready', function() {

   // Adaption IE6
   if(window.ie6) var 开发者_如何学编程heightValue='100%';
   else var heightValue='';

   // Selectors of the containers for switches and content
   var togglerName='h2.accordion_toggler_';
   var contentName='div.accordion_content_';


   // Position selectors
   var counter=1;   
   var toggler=$$(togglerName+counter);
   var content=$$(contentName+counter);

   while(toggler.length>0)
   {

      // Apply accordion
      new Fx.Accordion(toggler, content, {

         onComplete: function() { 
            var element=$(this.elements[this.previous]);
            if(element && element.offsetHeight>0) element.setStyle('height', heightValue);         
         },
         onActive: function(toggler, content) {
            toggler.addClass('open');
         },
         onBackground: function(toggler, content) {
            toggler.removeClass('open');
         }
      });

      // Set selectors for next level
      counter++;
      toggler=$$(togglerName+counter);
      content=$$(contentName+counter);
   }
});

The problem is that all section are open when the page loads and I wanted just the first top section and sub section.

Example:

Section 1
  Section 1.1
    Content 1.1
  Section 1.2
Section 2
Section 3
