后台管理的模板很多，vue本身就提供了完整的vue-template-admin，vue-admin-beautiful等后台管理系统化框架，但是这些框架正是因为成体系而显得繁重。假如你想搭建一个静态的后台管理模板页面和几个单独的菜单页面，直接就上框架是否就有点大材小用了呢 百分之九十以上的后台管理布局基本都是头部导航，侧边栏，主内容三部分组成。所以，将其单独摘出来为一个单独的轻量后台页面就很有必要了。
1. 效果展示
最常见的系统布局就是：左右布局。左侧是菜单栏，右侧是内容区，内容区又分为头部和展示区。。所以我们的效果显示如下：
目录结构呢，也很简单，因为不涉及请求，所以就是vue+element+vuex即可
这种就很适合做vue的静态页面演示开发，因为就只有几个页面，不涉及复杂的路由和权限啥的。
本博文是借鉴了这篇博客写的：vue+elementUi——实现后台管理系统的布局(sideBar+header+appMain)_element ui页面布局模板-CSDN博客
但是由于它的细节问题太多，在调试过程中也遇到了一些问题，所以重新写一篇调试完后的代码，主要的就是方便你我他。
2.关键代码
如果迁入自由的项目，可以复制对应的关键代码，store代码，配置对应的路由，自己调试也可。如果想直接拿来即用的，下面也会附上vue代码git地址。
index.vue 主页面，负责引入头部，侧边栏，主内容组件
