Javascript jquery单击导航，多个下拉菜单不起作用

当我单击“活页”或“单组织”时，我的下拉列表正在工作。但当它们都被点击时，它们都会保持向下并相互重叠。有人能帮我想一个办法，让他们回去，如果其他点击？下面是我的代码。谢谢

谢谢

在打开单击的列表的同时隐藏所有其他列表：

$('.click-nav li').click(function (e) {
    $('.click-nav li').not(this).find('ul').slideUp(200);
    $(this).find('ul').slideToggle(200);
    e.stopPropagation();
});

请
