java script problem

Hi,

I m use dynamic menu in my web software. I want to create active menu or say current menu of sub menu with css.

I just add "current" class in parent menu when click on submenu using java script like :

Code:

---

$('nav > ul > li > ul > li').click(function(event) {
                               
                                        $('nav > ul > li.current > ul').css('display','block');
                                        $('nav > ul > li').addClass('current').siblings().removeClass('current');
                                        //$('nav > ul > li').refreshTip();
                                        //event.preventDefault();
                               
                        })

---

I get current class in parent but sub menu href links are stop working.

any one can help me. please

thanks ,
Cristopher
