单击其他父菜单项时如何关闭所有其他打开的子菜单?

Question

我正在使用此代码链接。

当我像Services这样的Parent Menu时，sub-menu服务菜单将打开，但当我单击其他菜单时，其他子菜单也将打开。 我希望当我单击其他子菜单时，以前的子菜单将关闭。 请为我提供解决方案。 谢谢

基本上你需要知道 jQuery 中not()的概念，这样你就可以隐藏元素，除了点击一个。这是工作示例。

$('#menu-content').children("li").on('click', function(){
$("li[data-toggle='collapse']").not(this).addClass('collapsed');
$("li[data-toggle='collapse']").not(this).next('ul').removeClass('in');
//alert('clicked');
});

Answer 2

另一个版本的代码，对我有用。

$(".submenu").not('.submenu-child').click(function()
{
$(".submenu").not(this).find(".collapse").collapse('hide');
});

其中子菜单类应用于父菜单，子菜单子类应用于子菜单。
