layui 无限级多级菜单

layui 二级菜单 :https://gitee.com/hslr/layui_extension_modulemenu

我更改了下,变成了无线级菜单

layui.define('element',function(exports){ 
  var $ = layui.$,element = layui.element,tamp=new Date().getTime();
  var elem='#enian_menu_'+tamp;
    var menu_Ul = '<div class="layui-side layui-bg-black"><div class="layui-side-scroll" ><ul class="layui-nav layui-nav-tree" lay-shrink="" id="enian_menu_'+ tamp +'" lay-filter="enian_menu_'+ tamp +'"></ul></div></div>';

  var enian_menu = {
    render: render,
       setCheck:setCheck,
       v:"1.0.2019-1-9"
  };
