   <div>{{item.name}}</div>
     <div v-for="arry in item.itemse" :key="arry.id" :value='item.value' :label="item.label">

<script>
items: [

       id: 1,

       itemse: [{ id: 4, text: "冷凍可樂" }, { id: 5, text: "香草可樂" }]

      name: "雪碧",
      itemse: [{ id: 6, text: "冷凍雪碧" }, { id: 7, text: "青檸雪碧" }]

     name: "橙子",
     itemse: [{ id:8, text: "冷凍橙子" }, { id: 9, text: "新鮮橙子" }]
