element ui的三级导航菜单,点击任意一个第二级导航时,所有的三级导航都会被展开
如图,当我点击二级菜单如摄像头时,wifi和摄像头的子菜单都会同时展开或关闭
代码部分:
<template v-for="item in items">
<el-submenu :index="item.index">
<template slot="title">
<img :src="item.icon" alt="">{{ item.title }}
</template>
<template v-for="(subItem,i) in item.subs" >
<template v-if="subItem.sonSubs">
<el-submenu :index="subItem.index">
<template slot="title">
<img :src="'../../../static/img/'+subItem.mark+'.svg'" alt="">{{ subItem.title }}
</template>
<el-menu-item v-for="(sonSubItem,r) in subItem.sonSubs" :index="sonSubItem.index">
<img :src="'../../../static/img/'+sonSubItem.mark+'.svg'" alt="">{{sonSubItem.title}}
</el-menu-item>
</el-submenu>
</template>
</template>
</el-submenu>
</template>
