jquery - 导航栏折叠 JQuery 未触发 - Bootstrap 3.1.1

Question

我知道这个问题在 SO 上被问过很多次，但是我尝试过的所有答案都没有奏效。

我想为基于 Bootstrap 3.1.1 和 Shopify 构建的主题创建一个 Mega Menu。

菜单已经到位，但是我无法让菜单折叠!它只是在页面加载时停留在打开状态。

它在这个 Bootply 上运行完美

但是，在我的 staging server 上(Shopify) 它没有正确触发。 (密码:lukeskywalker)

Answer 1

在 style.css 文件的 CSS 代码中，您有:

.main-header ul, li {
  display: inline-block;
}

这将覆盖您的 .mega-dropdown-menu，它具有 display:none;，这就是您的菜单始终显示的原因。

不幸的是，即使我更改了您的菜单似乎也不起作用。我注意到在 bootply 示例中，当您单击打开菜单时，DOM 将更新为“打开”(显示在 dropdown-menu 类旁边)类和 before 和 after pseudo 也会被添加，这似乎不会发生在您的网站上。
