<template>
  <v-layout>
    <v-card contextual-style="dark" v-if="show">
      <span slot="header">
        一级主页面

      <div slot="body">主内容页
        <!-- <div v-for="item in listTittle" :key="item.id">{{item}}</div>         -->
        <!-- <div v-for="item in list" :key="item.id">
            <p>{{listTittle}}{{item.name }}</p>
          </div> -->
        <div>
