                <li><a href="#">Another action</a></li>

                <li role="separator" class="divider"></li>
                <li class="dropdown-header">Nav header</li>
                <li><a href="#">Separated link</a></li>
                <li><a href="#">One more separated link</a></li>
              </ul>

          </li>
        </ul>
      </div><!--/.nav-collapse -->
    </div>
  </nav>

区别在于第一个 ul 的最后一个 li 元素具有类 dropup 而不是 dropdown .
