Jquery四种苹果风格导航菜单(横向/竖向/向上/向下

一个基于jquery的苹果风格导航菜单，共有四种展示形式，横向的、竖向的、点击向上弹出的、点击向下弹出的。DIV结构。

非常酷的效果，看应提示即知。
部分代码如下：（你可以不看下面的代码^_^）

  <div id="dock">
   <div class="dock-container">
    <a class="dock-item" href="index.html"><span>Example&nbsp;1</span><img src="images/dock/home.png" alt="home" /></a>
    <a class="dock-item" href="example2.html"><span>Example&nbsp;2</span><img src="images/dock/email.png" alt="contact" /></a>
    <a class="dock-item" href="example3.html"><span>Example&nbsp;3</span><img src="images/dock/portfolio.png" alt="portfolio" /></a>
    <a class="dock-item" href="all-examples.html"><span>All&nbsp;Examples</span><img src="images/dock/music.png" alt="music" /></a>
