hi guys, I'm working with a jquery accordion plugin. Its automatic, so even if you're not hovering or clicking over it, the panel moves smoothly at a set time. My problem is I want to add some effects on it like when the panel opens or gets active a child element (e.g Paragraph ) fades in.

  $('#accordion > li')._**what should I use here?**_(
                    function () {
                        var $this = $(this);
                        $this.stop().animate({'width':'480px'},500);
                        $('.heading',$this).stop(true,true).fadeOut();
                        $('.bgDescription',$this).stop(true,true).slideDown(500);
                        $('.description',$this).stop(true,true).fadeIn();
                    },
                    function () {
                        var $this = $(this);
                        $this.stop().animate({'width':'115px'},1000);
                        $('.heading',$this).stop(true,true).fadeIn();
                        $('.description',$this).stop(true,true).fadeOut(500);
                        $('.bgDescription',$this).stop(true,true).slideUp(700);
                    }
                );

What jquery api should I use to get the current/active/opened panel and bring in some effect. Thanks
