        i = links.length;
    while(i--) {
          links[i].onclick = function() {
              var str = this.hash.replace(/#/, ''),
                  dd = document.getElementById(str),
                  childrens = dd.parentNode.children,
                  i = childrens.length;

              while(i--) {
                  var node = childrens[i];
                  if(node.nodeName == 'DD' && node.id != str) {
                      node.style.display = '';
                  }
             }
             dd.style.display = (dd.style.display == '') ? 'block' : '';
             return false;
         };
    }
};
