在这里的演示界面中：
https://blackrockdigital.github.io/startbootstrap-sb-admin-2/pages/index.html
如果添加css类 ＆＃34;的导航栏固定顶＆＃34;到元素
<nav class="navbar navbar-default navbar-static-top" role="navigation" style="margin-bottom: 0">
你得到以下元素：
<nav class="navbar navbar-default navbar-static-top navbar-fixed-top" role="navigation" style="margin-bottom: 0">
现在，如果您尝试滚动页面的主要内容，内容仍会按预期滚动。
但是如果您尝试滚动导航菜单，则它不可滚动。
如何使导航菜单像主要内容一样可滚动但仍保留固定标题？

**You just need to take sidebar out of navbar like below**
<nav class="navbar navbar-default navbar-fixed-top" role="navigation" style="width: 100%;">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>

答案 1 :(得分：0)
添加位置：相对于新导航栏的样式：
<nav class="navbar navbar-default navbar-static-top navbar-fixed-top" role="navigation" style="margin-bottom: 0;position:relative">
它将返回滚动行为，据我所见，它不会弄乱设计。
答案 2 :(得分：0)
请说清楚你真正想要的......
如果您希望侧边栏是静态的，请尝试使用
.sidebar {
position: fixed !important;
}
让我知道你真正想要的是什么。
答案 3 :(得分：0)
你必须得到这个组件：
<div class="navbar-default sidebar" role="navigation" style="left: 0px;">
...
</div>
在elemnt <nav class="navbar navbar-default navbar-static-top navbar-fixed-top" role="navigation" style="margin-bottom: 0">...中加入<div id="page-wrapper">...并将left: 0px;应用为样式（如代码示例所示）。
因为，当您将类navbar-fixed-top应用于元素nav时，它会获得影响左侧菜单的position: absolute属性，因此通过将其移动到主组件所在的组件中来提供滚动再次聚在一起。以下是这些组件的完整来源：
<div id="wrapper">
