最简单的方法就是把二级菜单的样式设置为:

1:oe_secondary_submenu {display:none}

2:在点击的时候显示二级菜单:

$(".oe_secondary_submenu").data("onShow")=false //一开始状态为隐藏

$(".oe_secondary_menu_section").click(function(){

if($(".oe_secondary_submenu").data("onShow")){ //切换二级菜单的同时改变状态

$(".oe_secondary_submenu").hide()

$(".oe_secondary_submenu").data("onShow",false)

}else{

$(".oe_secondary_submenu").show()

$(".oe_secondary_submenu").data("onShow",true)

}

})
