html - Bootstrap 4 - 响应式水平导航

Question

我遇到了 Bootstrap 4 导航的问题，如果导航链接的容器宽度太小，导航链接就会悬垂。移动设备通常就是这种情况。

这是一个例子:http://codepen.io/anon/pen/ZLKGrx

<div class="container">
  <div class="row">
    <div class="col-6 offset-3 columnbg">
      <ul class="nav nav-pills">
        <li class="nav-item">
          <a class="nav-link active" href="#">LongTabName</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">LongTabName</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">LongTabName</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#">LongTabName</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#">LongTabName</a>
        </li>
      </ul>
    </div>
  </div>
</div>

我想实现适合较小显示器的东西。我该怎么做？

Bootstrap 专为移动优先而构建。您遇到此问题的唯一原因是您没有完全实现 navbar :
