我在我的应用程序中使用来自 Bootstrap 的导航的 dropdown 选项:当我点击下拉开关(在我的例子中是 a 元素)时，ul 下拉列表部分不会显示，但仅在非折叠 View (即桌面)中显示。在移动设备中，折叠时它会正常运行。请注意，除了 Bootstrap 的自动行为外，其余 HTML/CSS 没有任何变化。

当我点击后检查它时，ul 及其元素相应地突出显示，并且 ul 具有内联 display: block应该，所以元素都在那里。由于某种我无法弄清楚的原因，它们根本不呈现。

起初，我认为这可能是z-index 问题，但ul 高于一切。

顺便说一句，它以前工作没有问题，但我无法完全追溯到那个状态。

有人知道为什么会发生这种情况，或者我如何找到原因？

最佳答案

您的问题是 overflow: hidden 在两个 div 上。

从你的 CSS 中删除它:

.navbar {
  overflow: hidden;
}
.navbar-2nd {
  overflow: hidden;
}
