What happened to nav-header class?
提问by Timothy Shields
With Bootstrap 2.3.2 you could use the nav-headerclass as follows to create a grouped list.
使用 Bootstrap 2.3.2，您可以nav-header按如下方式使用该类来创建分组列表。
<ul class="nav nav-pills nav-stacked">
<li class="nav-header">Group A</li>
<li><a href="/items/1">Item 1</a></li>
<li><a href="/items/2">Item 2</a></li>
<li><a href="/items/3">Item 3</a></li>
<li class="nav-header">Group B</li>
<li><a href="/items/4">Item 4</a></li>
<li><a href="/items/5">Item 5</a></li>
</ul>
In Bootstrap 3.0.0 the nav-headerclass seems to have been removed, though I can't find any mention of it being removed in the docs. I also can't find a replacement.
在 Bootstrap 3.0.0 中，nav-header该类似乎已被删除，但我在文档中找不到任何提及它已被删除的内容。我也找不到替代品。
Is this kind of functionality still present? If so, what's the new way?
这种功能还存在吗？如果是这样，新的方法是什么？

Regarding LESS files and Github project, nav-listand nav-headerhas never existed in Bootstrap 3. I guess it has been forgotten.
关于LESS文件和Github上项目，nav-list并且nav-header从未在引导3.存在我猜想它已经被遗忘了。
You can get a similar behavior using this kind of hack:
您可以使用这种 hack 获得类似的行为：
ul {
width: 300px;
margin: 20px;
}
.nav > li.nav-header > a {
cursor: default;
font-size: 12px;
font-weight: bold;
text-transform: uppercase;
}<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet"/>
<ul class="nav nav-pills nav-stacked">
<li class="nav-header"><a>Group A</a></li>
<li><a href="/items/1">Item 1</a></li>
<li><a href="/items/2">Item 2</a></li>
<li><a href="/items/3">Item 3</a></li>
<li class="nav-header"><a>Group B</a></li>
<li><a href="/items/4">Item 4</a></li>
<li><a href="/items/5">Item 5</a></li>
</ul>Wrap your header in a <a>, add the class .disabledand create your own .nav-headerclass.
将您的标题包裹在一个 中<a>，添加类.disabled并创建您自己的.nav-header类。
EDITAccording to this issueand this changelog, nav-listhas been replaced by list-group, but you don't have any real way to get the same behavior for headers.

Even though your nav list isn't a dropdown using the dropdown-headercss class will work.
即使您的导航列表不是使用dropdown-headercss 类的下拉列表也可以使用。
<ul class="nav nav-pills nav-stacked">
<li class="dropdown-header">Group A</li>
<li><a href="/items/1">Item 1</a></li>
<li><a href="/items/3">Item 3</a></li>
<li class="dropdown-header">Group B</li>
<li><a href="/items/4">Item 4</a></li>
<li><a href="/items/5">Item 5</a></li>
</ul>
