[scudobravo]

Mi rispondo da solo

Usando mootools:

              window.addEvent('domready', function(){
                $$('.toggler').each(function (el){
                    el.addEvent('click',function(){
                        var myCol = el.getStyle('color');
                        if(myCol == '#ec7324') { this.setStyle('color', '#000000'); } else { this.setStyle('color', '#ec7324'); }
                    });
                });
            });
            function toggleMe(a){
              var e = document.getElementById(a);
              if(e.style.display=="none"){
                e.style.display="block";
              } else {
                e.style.display="none";
              }
              return true;
            }
