Bootstrap菜单在移动模式下不能正确显示

你好，我有这个导航工作。 一切都OK桌面模式，但在移动导航中断。 如果我在header div上使用@media css选项，可以解决这个问题。

请参阅下面的代码为导航菜单：请注意，我使用bootrap cdn。

             <span class="header-info phone"><i class="fa fa-phone fa-lg"></i> Call Us: 0800 123 456 789</span>      <span class="header-info email"><i class="fa fa-envelope-o fa-lg"></i> mail@yoursite.com</span>  
               </div>
                <div class="navbar-header"><a class="navbar-brand" href="#">TAJ</a> 
                  <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-menubuilder"><span class="sr-only">Toggle navigation</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span>
                  </button>
              </div>
              <div class="collapse navbar-collapse navbar-menubuilder">
                  <ul class="nav navbar-nav navbar-right">
                      <li><a href="/">Home</a>
                      </li>
                      <li><a href="/products">Products</a>
                      </li>
                      <li class="dropdown"><a href="/about-us" class="dropdown-toggle" data-toggle="dropdown">About Us <b class="caret"></b></a>
                          <ul class="dropdown-menu" role="menu">
                              <li><a href="#">Test2</a>
                              </li>
                          </ul>
                      </li>
                      <li class="dropdown"><a href="/contact" class="dropdown-toggle" data-toggle="dropdown">Contact Us <b class="caret"></b></a>
                          <ul class="dropdown-menu" role="menu">
                              <li><a href="#">About</a>
                              </li>
                          </ul>
                      </li>
                  </ul>
              </div>
          </div>
      </div>
