html - Bootstrap 3.3 导航栏下拉文本溢出容器

Question

我正在尝试使用 bootstrap 的下拉元素创建一个通知小部件，就像在 Facebook 或 Stack Overflow 中使用的那样。内容物现在正在破裂并流出容器。

<nav class="navbar navbar-default">
  <div class="container-fluid">
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
      <li><a href="#">Link</a></li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
        <ul class="dropdown-menu" style="width: 300px">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here Something else here Something else here Something else here Something else here Something else here Something else here Something else here</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">Separated link</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">One more separated link</a></li>
        </ul>
      </li>
    </ul>
  </div>
</nav>

我的列表项如下所示:

<li><a>
<div class="row">
  <div class="col-md-4">
    <img/>
  </div>
  <div class="col-md-8">
    <b>Title</b><br />
    <span>Description</span>
  </div>
</div>
</a>
</li>

我尝试添加 clearfix 并将宽度分配给跨度，但没有任何帮助。

您需要做的就是将它添加到您的 css 中，它将使您的 a 的内容很好地包装:

.navbar .nav li .dropdown-menu li a {
  white-space: normal;
}
