Bootstrap

1、1vue系统平台模板(element-ui)--头部侧边栏框架搭建

最近在整理系统平台的demo,记录一下，后续可以继续更新
1、基本样式
列表
柱状图
折线图
饼图
2、代码结构
在这里插入图片描述
3、头部和侧边栏
top-menu

<template>
    <div class="topbar-title">
        <el-row>
          <el-col :span="24">

                <el-menu-item v-for="(item,i) in menu" :key="i" :index="item.url">
                    <span slot="title">{{ item.title }}</span>
                </el-menu-item>
            </el-menu>
