自举4个标签不卷绕

Question

问题发生在阿尔法6但不阿尔法5

在自举3个标签将换到下一行，以便它们可以在更小的屏幕尺寸来使用。

在自举4他们不包裹和戳关闭屏幕的一侧。这是Bootstrap 4文档的例子。

我如何让它在引导3换什么样的？

（黑色轮廓显示小视口。在以前的版本标签会换到新的生产线，因此所有将是可见的黑线内）

Answer 1

导航标签，像其他组件现在是Flexbox的。只需使用flex-wrap即可。

<ul class="nav nav-tabs flex-wrap" role="tablist"> 
     <li class="nav-item"> 
      <a class="nav-link active" data-toggle="tab" href="#home" role="tab">Home</a> 
     </li> 
     <li class="nav-item"> 
      <a class="nav-link" data-toggle="tab" href="#profile" role="tab">Profile</a> 
     </li> 
     ... 
</ul>

我不认为这是一个 “问题”，而是 “设计”。

另一种可能更具响应性的方法是使用flex-column，但仅限于xs宽度。这种方式是垂直堆叠而不是缠绕。

<ul class="nav nav-tabs flex-column flex-md-row" role="tablist"> 
     <li class="nav-item"> 
        <a class="nav-link active" data-toggle="tab" href="#home" role="tab">Home</a> 
     </li> 
     <li class="nav-item"> 
        <a class="nav-link" data-toggle="tab" href="#profile" role="tab">Profile</a> 
     </li> 
     ... 
</ul>

似乎是具体的问题要引导的第4版使用的是：
