Question

我正在尝试使用bootstrap的下拉元素创建类似Facebook中使用的通知小部件或Stack Overflow。内容现在正在破碎并流出容器。

<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并将宽度分配给范围，但没有任何帮助。

Answer 1

您需要做的就是将其添加到您的CSS中，它会使您的a内容很好地包装：

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

Answer 2

默认情况下，Bootstrap尝试使用white-space: nowrap;将所有文本包装在下拉列表中。您可以使用white-space: normal;撤消该操作。

.dropdown-menu>li>a {
  white-space: normal !important;
}
