Hi sloy,

Please take a look at the examples on this thread
http://wordpress.org/support/topic/plugin-advanced-sidebar-menu-accordion-menu

Half way through the thread broke into two columns so you will have to look on the right side.

I believe the final code was something like this

jQuery(document).ready( function($) {
	//Adds a class to keep track if we are on a parent of child page
	$('.current_page_item').next().addClass('sidebar-menu-hover');

	//Make the menu open and close by hovering when on a parent page
    $(".child-sidebar-menu.sidebar-menu-hover > li > a").hover(function(){
    	//Slides open and closed the grandchild menu
         $(this).parent().find('ul').slideToggle(400);
         			return false;
     }, function(){
    	 return false;
     });

    //Make the menu open and close by clicking if on a child or grandchild page
    $(".child-sidebar-menu > li > a").not(".child-sidebar-menu.sidebar-menu-hover > li > a").click(function(){
    	//If there all no children link the link return Otherwise stop the link
    	if( $(this).parent().find('ul').slideToggle(400).length > 0 ){
    		return false;
    	} else {
    		return true;
    	}
     });

    //Initially hides the grandchild menu
    $('.child-sidebar-menu ul').hide();

    //Initially show the grandchild menu if on a grandchild or child pages
    $('.child-sidebar-menu ul li.current_page_item').parent().show();
    $('.child-sidebar-menu ul li.current_page_item ul').show();
    $('.child-sidebar-menu li.current_page_item ul').show();
});

Hope this helps.

Cheers
