How does elementUI's navmenu cycle through different tags in v-for?

  <el-menu :default-active="activeIndex" class="el-menu-demo" mode="horizontal" @select="handleSelect">
  <el-menu-item index="1"></el-menu-item>
  <el-submenu index="2">
    <template slot="title"></template>
    <el-menu-item index="2-1">1</el-menu-item>
    <el-menu-item index="2-2">2</el-menu-item>
    <el-menu-item index="2-3">3</el-menu-item>
    <el-submenu index="2-4">
      <template slot="title">4</template>
      <el-menu-item index="2-4-1">1</el-menu-item>
      <el-menu-item index="2-4-2">2</el-menu-item>
      <el-menu-item index="2-4-3">3</el-menu-item>
    </el-submenu>
  </el-submenu>
  <el-menu-item index="3" disabled></el-menu-item>
</el-menu>

I want to pass in the data to achieve this effect, but different types of menu labels are different, v-for can only be written in the tag, how can I control the judgment? 

 <el-menu
      default-active="2"
      class="el-menu-vertical-demo"
      @open="handleOpen"
      @close="handleClose">
       <el-submenu index="1" v-for="menu in menus" v-bind:key="menu.id">
        <template slot="title" v-if="menu.type == 1" >
        <i :class="menu.icon"></i>
        <span slot="title">{{ menu.name }}</span>
        </template>
      </el-submenu>
      <el-menu-item index="2" v-esle>
       <template slot="title">
          <i :class="menu.icon"></i>
          <span>{{ menu.name }}</span>
        </template>
        <el-menu-item-group>
          <template slot="title"></template>
          <el-menu-item index="1-1">1</el-menu-item>
          <el-menu-item index="1-2">2</el-menu-item>
        </el-menu-item-group>
      </el-menu-item>
    </el-menu>

you can render

with < template > with v-for. 
<ul>
  <template v-for="item in items">
    <li>{{ item.msg }}</li>
    <li class="divider"></li>
  </template>
</ul>
