html - 获取问题引导左侧菜单栏，想要添加下一个更多子菜单项

Question

<li class="drop-menu-tab">
    <a class="dropmenu" ><i class="icon-folder-close-alt"></i><span> Employee</span></a>
        <ul>
            <li><a class="submenu" href="<?php echo base_url(); ?>emp/fulltime"><i class="icon-edit"></i><span class="hidden-tablet">Full Time</span></a></li>                                  
            <li id="mainmenulink"><a class="submenu" href="<?php echo base_url(); ?>emp/parttime"><i class="icon-edit"></i><span class="hidden-tablet"> Part Time</span></a></li>
        </ul>   
</li>

我必须添加下一个更多的子菜单..

例如。

Employee > Full Time > Day Shift
Employee > Full Time > Night Shift

我尝试了多种方法..但是打开正确的标签关闭..请建议可能的脚本

仅供参考：使用“引导 v2.3.1”

您在编写时遇到拼写错误，<span>您已将其编写为<spanc>

将其更改为

<span> Employee</span>

您可以通过以下方式获得所需的输出

li{
  list-style: none;
}
ol.breadcrumb li+li:before {
  padding: 8px;
  color: black;
  content: "\003e";
}
