vue-admin-template 默认没有开启顶部导航，可通过如下步骤进行开启。

开启步骤

复制 vue-element-admin 必要组件，到 template 对应的目录下。

@/layout/components/TagsView 文件夹

@/store/modules/tagsView.js 文件

添加标签
@/layout/components/AppMain.vue 添加：

<template>
 <section class="app-main">
   <transition name="fade-transform" mode="out-in">
     <keep-alive :include="cachedViews">   <!-- 新增  -->
       <router-view :key="key" />
     </keep-alive>           <!-- 新增 -->
   </transition>
 </section>
</template>

修改 @store/index.js

import Vue from 'vue'
import Vuex from 'vuex'
import getters from './getters'
import app from './modules/app'
import settings from './modules/settings'
import user from './modules/user'
import tagsView from './modules/tagsView'  //新增

Vue.use(Vuex)

const store = new Vuex.Store({
  modules: {
    app,
    settings,
    user,
    tagsView  //新增
  },
  getters
})

export default store

修改 /src/store/getters.js

const getters = {
  sidebar: state => state.app.sidebar,
  device: state => state.app.device,
  token: state => state.user.token,
  avatar: state => state.user.avatar,
  name: state => state.user.name,
  visitedViews: state => state.tagsView.visitedViews,  //新增
  cachedViews: state => state.tagsView.cachedViews  //新增
}
export default getters

修改 /src/layout/components/index.js

export { default as Navbar } from './Navbar'
export { default as Sidebar } from './Sidebar'
export { default as AppMain } from './AppMain'
export { default as TagsView } from './TagsView/index.vue'   //新增

修改 /src/store/modules/setting.js

const { showSettings, tagsView, fixedHeader, sidebarLogo } = defaultSettings   //新增tagsView

const state = {
  tagsView: tagsView,   //新增
  showSettings: showSettings,
  fixedHeader: fixedHeader,
  sidebarLogo: sidebarLogo
}

修改 /src/layout/index.vue

<template>
  <div :class="classObj" class="app-wrapper">
    <div v-if="device==='mobile'&&sidebar.opened" class="drawer-bg" @click="handleClickOutside" />
    <sidebar class="sidebar-container" />
    <div class="main-container">
      <div :class="{'fixed-header':fixedHeader}">
        <navbar />
        <tags-view v-if="needTagsView"/>   <!-- 新增 -->
      </div>
      <app-main />
    </div>
  </div>
</template>

<script>
import { Navbar, Sidebar, AppMain , TagsView} from './components'   //新增 TagsView
import ResizeMixin from './mixin/ResizeHandler'

export default {
  name: 'Layout',
  components: {
    Navbar,
    Sidebar,
    AppMain,
    TagsView   //新增
  },
  mixins: [ResizeMixin],
  computed: {
    sidebar() {
      return this.$store.state.app.sidebar
    },
    device() {
      return this.$store.state.app.device
    },
    fixedHeader() {
      return this.$store.state.settings.fixedHeader
    },
    needTagsView() {   //新增
      return this.$store.state.settings.tagsView   //新增
    },
    classObj() {
      return {
        hideSidebar: !this.sidebar.opened,
        openSidebar: this.sidebar.opened,
        withoutAnimation: this.sidebar.withoutAnimation,
        mobile: this.device === 'mobile'
      }
    }
  },
  methods: {
    handleClickOutside() {
      this.$store.dispatch('app/closeSideBar', { withoutAnimation: false })
    }
  }
}
</script>

修改 /src/setting.js

module.exports = {

  title: 'Vue Admin Template',

  /**
   * @type {boolean} true | false
   * @description Whether fix the header
   */
  fixedHeader: false,

  /**
   * @type {boolean} true | false
   * @description Whether show the logo in sidebar
   */
  sidebarLogo: false,

  /**
   * @type {boolean} true | false
   * @description Whether need tagsView
   */
  tagsView: true   //新增
}
