twitter-bootstrap – bootstrap 4导航栏导航标签

在bootstrap 4中,我尝试使用固定的底部导航栏,当单击链接时,使用的内容来自4个选项卡.
回到早期的引导程序,我曾经工作但试图让它与4一起工作并不适合我.有人能指出我在这里错过的方向吗？

解决方法

您只需要在navbar-nav中包含nav类… @H_502_9@演示：https://www.codeply.com/go/IzQdCtwy78

<ul class="navbar-nav nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="#tab1">test1</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#tab2" data-toggle="tab">test2</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#tab3" data-toggle="tab">test3</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#tab4" data-toggle="tab">test4</a>
            </li>
       </ul>
