官网上没有太多的说明

废话不多说，直接上代码

1.复制vue element admin必要组件

AppMain.vue覆盖一下

2.修改一些文件

/src/store/index.js

/src/store/getters.js

/src/layout/components/index.js

/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="{hasTagsView:needTagsView}" class="main-container">
            <div :class="{'fixed-header':fixedHeader}">
                <navbar/>
                <tags-view v-if="needTagsView"/>
            </div>
            <app-main/>
        </div>
    </div>
</template>

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

  export default {
    name: 'Layout',
    components: {
      Navbar,
      Sidebar,
      AppMain,
      TagsView
    },
    mixins: [ResizeMixin],
    computed: {
      sidebar() {
        return this.$store.state.app.sidebar
      },
      device() {
        return this.$store.state.app.device
      },
      fixedHeader() {
        return this.$store.state.settings.fixedHeader
      },
      needTagsView() {
        return this.$store.state.settings.tagsView
      },
      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>

    .app-wrapper {
        @include clearfix;
        position: relative;

        width: 100%;

        &.mobile.openSidebar {
            position: fixed;
            top: 0;
        }
    }

    .drawer-bg {
        background: #000;
        opacity: 0.3;
        width: 100%;
        top: 0;
        height: 100%;
        position: absolute;
        z-index: 999;

    .fixed-header {

        top: 0;
        right: 0;
        z-index: 9;
        width: calc(100% - #{$sideBarWidth});
        transition: width 0.28s;
    }

    .hideSidebar .fixed-header {
        width: calc(100% - 54px)
    }

    .mobile .fixed-header {
        width: 100%;
    }
</style>

/src/store/modules/setting.js

/src/setting.js

3结果

4控制台报错

这是因为拷贝的TagsView组件默认开启了权限
/src/layout/components/TagsView/index.js
