thinkphp框架怎么做一个三级菜单

thinkphp框架onethink后台支持三级菜单

onethink后台支持三级菜单,CMS管理后台1.0版本本身不支持三级菜单，稍加改动，即可支持无限级分类

/**

* 获取控制器菜单数组,二级菜单元素位于一级菜单的'_child'元素中

基于Bootstrap和AdminLTE进行二次开发,手机、平板、PC均自动适配,无需要担心兼容性问题

多语言

不仅仅后台开发支持多语言,同时视图部分和JS部分仍然共享同一个语言包,语法相同且自动加载

模块化开发

控制器、模型、视图、JS一一对应,使用RequireJS进行JS模块化管理,采用Bower进行前端包组件管理

CRUD

控制台进行一键生成控制器、模型、视图和JS文件,同时可一键生成后台权限节点和菜单栏

丰富的插件

基于ThinkPHP行为功能实现的插件机制,拥有丰富的插件和扩展,可直接在线安装卸载
