如何在点击一个li时获得所有li？

Question

我想点击Li时，另一个同样的ul的Li在ul width class“container-bar”上显示我。

<ul>
     <li class="item-menu dropdown">

          <ul class="sub-menu">`
              <li class="sub-item-menu"><a href="/Properteis      /PropertiesIndex"><span class="fa fa-file-text"></span>one-o</a></li>
              <li class="sub-item-menu"><a href="/Properteis/PropertiesUnit"><span class="fa fa-pie-chart"></span>one-t</a></li>
              <li class="sub-item-menu"><a href="/Properteis/PropertyCategories"><span class="fa fa-object-group"></span>one-th</a></li>                  
          </ul>
     </li>
</ul>
