element-ui实现动态菜单栏 并处理菜单栏折叠文本不隐藏问题
一：创建 NavMenu.vue 动态添加菜单栏（递归实现）
<template>
<div>
<template v-for="navMenu in navMenus">
//一级菜单
<el-menu-item v-if="navMenu.childs===null&&navMenu.entity&&navMenu.entity.state==='ENABLE'"
:key="navMenu.entity.id" :data="navMenu" :index="navMenu.entity.name" :route="navMenu.entity.value">
<i :class="navMenu.entity.icon"></i>
<span slot="title">{{navMenu.entity.alias}}</span>
</el-menu-item>
//多级菜单
<el-submenu v-if="navMenu.childs&&navMenu.entity&&navMenu.entity.state==='ENABLE'" :key="navMenu.entity.id"
:data="navMenu" :index="navMenu.entity.name">
<template slot="title">
<i :class="navMenu.entity.icon"></i>
<span> {{navMenu.entity.alias}}</span>
</template>
<NavMenu :navMenus="navMenu.childs"></NavMenu>
</el-submenu>
</template>
</div>
</template>
调用NavMenu.vue
<template>
<div id="app">
<el-radio-group v-model="isCollapse" style="margin-bottom: 20px;">
<el-radio-button :label="false">展开</el-radio-button>
<el-radio-button :label="true">收起</el-radio-button>
</el-radio-group>
<el-menu default-active="authManage" class="el-menu-vertical-demo" @select="menuSelected" background-color="#333743"
text-color="#909399" active-text-color="#909399" :collapse="isCollapse">
<NavMenu :navMenus="leftMenus"></NavMenu>
</el-menu>
</div>
</template>

问题如图：

第三步:
将NavMenu.vue中的
修改为即可
<template>
<fragment>
<template v-for="menu in menus">
<el-submenu v-if="menu.children && menu.children.length >= 1" :index="menu.menuId + ''" :key="menu.menuId">
<template slot="title">
<i :class="menu.icon">i>
<span slot="title">{{menu.menuName}}span>
template>
<z-menu :menus="menu.children">z-menu>
el-submenu>
<el-menu-item v-else :index="menu.menuId + ''" @click="handleRouter(menu)" :key="menu.menuId">
<i :class="menu.icon">i>
<span slot="title">{{menu.menuName}}span>
el-menu-item>
template>
fragment>
