JQuery ZTree简单使用
@(JavaScript)[jQuery, ztree, 入门]
基本概述
zTree 是一个依靠 jQuery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 zTree 最大优点。专门适合项目开发，尤其是 树状菜单、树状数据的Web显示、权限管理等等。
zTree 是开源免费的软件（MIT 许可证）。在开源的作用下，zTree 越来越完善，目前已经拥有了不少粉丝，并且今后还会推出更多的 zTree 扩展功能库，让 zTree 更加强大。 ――参考《百度百科》

PS：zTree的官方API文档和demo挺详细的，值得一读。
案例
使用标准json数据构造ztree
