html自定义垂直导航菜单（目前只支持上级+下级两级菜单）
由于工作的需要，昨天花了三个多小时的事件整理了一份关于垂直导航二级菜单，可以通过js配置的方式初始化菜单box（测试环境：chrome 49、IE 10、IE edge）。
no pic u say a j8? 好吧，先上效果图（由于下面是gif，所以一帧一帧的感觉不流畅。讲道理，事实上，切换非常流畅，自行下载看Demo）。
js配置方式：
配置menuBox的方式：menuBox.init(config);
这里的config有三个属性：
menuBoxId（必需，你要配置的菜单根节点所在元素的Id）
multiple（可选，是否可以同时打开多个上级菜单，默认是false，也就是最多显示一个上级菜单的子菜单）
openIndex（可选，初始化要打开上级菜单的index数组，如果你要传值，按照格式应该是数字数组）
//配置第一个手风琴的基本参数
var config01 = {
//配置菜单的MenuBoxId
menuBoxId: "#menuBox01",
//是否可以打开多个上级菜单的子菜单
multiple: false,
//初始化打开的
openIndex: [3, 4, 5]
}
menuBox.init(config01);
然后看下两个菜单Box的配置：
第一个菜单Box：可以同时打开多个上级菜单，初始化的时候打开第0、1个。
//配置第一个手风琴的基本参数
var config01 = {
//配置菜单的MenuBoxId
menuBoxId: "#menuBox01",
//是否可以打开多个二级菜单
multiple: true,
//初始化打开的
openIndex: [0,1]
}
menuBox.init(config01);
第二个菜单Box：不可以打开多个上级菜单，初始化的时候打开第1个，如果传入数组有多个值，默认打开第一个有效的index上级菜单。
//配置第二个手风琴的基本参数
var config02 = {
//配置菜单的MenuBoxId
menuBoxId: "#menuBox02",
//是否可以打开多个二级菜单
multiple: false,
//初始化打开的
openIndex: [-1, 1]
}
menuBox.init(config02);
用到的知识点：
1、flexbox（在ie9及以下布局不兼容，但是还是可以正常看到切换效果）。
2、css3 transform配合transition实现箭头的旋转切换。
3、打开菜单：$().slideDown()、关闭菜单：$().slideUp()、切换菜单：$().slideToggle()。有时间我会修改为css3动画实现切换，尽量不用jquery。
4、<i>标签引用图标font-awesome
