 <div class="mainmenu nav">
 <nav>
<ul id="nav">
<li><a href="services.php">Service</a>
	<ul> 
	 <li><a href="#">Menu</a></li>                  
   <li class="subNav"><a href="#">Menu2</a>
					<ul class="subNav">
						 <li><a href="#">Piano</a></li>                                   	 <li><a href="#"> Couch</a></li>
						 <li><a href="#">Appliances</a></li>
					 </ul>
          </li> 
			</ul> 
</li> 
</ul>
</nav>
</div>

将光标放在结果页面中，你会看到输出，我想要一个人把光标带到MENU2，它应该浮动到左侧而不是向下。

提前致谢。

在这里，你需要让包含subnav的li相对显示，这样子子菜单可以在左边绝对定位200px，在li中引用0的顶部。
