Bootstrap - 菜单下拉列表推下内容

Question

下拉菜单将内容向下推送。

我已经尝试了所有我能找到的“修复”。相对位置、绝对位置、静态位置。但是有了这些，它仍然会向下推，虽然当动画结束时，下面的内容会向上跳跃一点（链接也在左侧/右侧）。

（Bootstrap 上是否还有其他菜单选项可以显示侧边栏？）

我查看了 Stackoverflow 上的所有问题。 相对于 ul 的位置，绝对的，静态的。也把所有的放在一个div里，试过Z-index。

@media (min-width: 576px), (max-width: 768px) {

在您的示例中，如果您为 .navbar 提供任何位置，它只会被默认的引导 css 样式覆盖，但您可以执行以下操作：

.navbar {
        padding-top: 3%;
        padding-bottom: 1%;
        display: flex;
        justify-content: center;

        position: absolute !important; //now position is not overriden
        top: 0; 
        width: 100%;
        background-color: #fff; //just for dropdown to be visible
    }

现在导航不会下推内容。 Check please my example on codepen.
