【问题描述】：
我想在这个垂直菜单栏上创建一个子菜单。我知道我必须更改 css 才能制作子菜单，但我不能很好地使用 css3。我正在使用的 css 文件不提供子菜单代码。真正的html代码是这样的
<body><ul class="ca-menu">
<li>
<a href="pagehome.php">
<span class="ca-icon">D</span>
<div class="ca-content">
<h2 class="ca-main">Home</h2>
</div>
</a>
</li>
<li>
<a href="settingpage.php">
<span class="ca-icon">S</span>
<div class="ca-content">
<h2 class="ca-main">Setting</h2>
</div>
</a>
</li>
</ul></body>
当用户将鼠标悬停到此菜单（设置）时，我想再添加两个垂直子菜单。像这样
<body><ul class="ca-menu">
<li>
<a href="pagehome.php">
<span class="ca-icon">D</span>
<div class="ca-content">
<h2 class="ca-main">Home</h2>
</div>
</a>
</li>
<li class='has-sub'>
<a href="settingpage.php">
<span class="ca-icon">S</span>
<div class="ca-content">
<h2 class="ca-main">Setting</h2>
</div>
</a>
<!-- this UL will be openning for new submenu
<ul>
<li><a href="settingpage.php"> <!-- Edit Here
<span class="ca-icon">S</span> <!-- Edit Here
<div class="ca-content"> <!-- Edit Here
<h2 class="ca-main">Submenu 1</h2><!-- Edit Here
</div></a>
</li>
<li> <a href="settingpage.php"> <!-- Edit Here
<span class="ca-icon">S</span> <!-- Edit Here
<div class="ca-content"> <!-- Edit Here
<h2 class="ca-main">Submenu 2</h2><!-- Edit Here
</div></a>
</li>
</ul>
this UL will be end for new submenu -->
</li>
</ul></body>

你能做个小提琴吗？ jsfiddle.net 如果我们能执行这些东西，将会有很大帮助。

jsfiddle.net/v8k7k/1 这是我正在做的例子。箭头是我想要子菜单所在的位置，缩放的字体实际上是像这个演示一样的图标tympanus.net/Tutorials/CreativeCSS3AnimationMenus/index3.html
