Twitter bootstrap 小型设备上的水平导航栏滚动

我用的是bootstrap4。我使用创建了第二个导航栏

<div class="nav-active-border b-danger bottom">
    <ul class="nav nav-active-border b-warning flex-row">
       <li class="nav-item">Link 1</li>
       <li class="nav-item">Link 2</li>
       <li class="nav-item">Link 3</li>
       <li class="nav-item">Link 4</li>
       <li class="nav-item">Link 5</li>
       <li class="nav-item">Link 6</li>
       <li class="nav-item">Link 7</li>
       <li class="nav-item">Link 8</li>
       <li class="nav-item">Link 9</li>
    </ul>
</div>

链接1
链接2
链接3
链接4
链接5
链接6
链接7
链接8
链接9

然而，这在手机上显示在两行中有多个项目。如何在手机上为这些导航项目创建一个水平滚动条，该滚动条带有仅用于手机布局的指示器。它在台式机和笔记本电脑上显示完美

我正试图在谷歌上实现同样的目标

我使用flexbox实用程序类通过Bootstrap 4创建了类似的东西

使用一个小jQuery来切换

justify content end

类，该类将导航项目对齐到右侧，而不是左侧。您可以切换以向任意方向滑动导航。CSS转换用于滑动动画

演示：

CSS
