如何使用VueJS遍历嵌套数据

<template>
  <div>
    <ul>
      <li v-for="item in items" :key="item.id">
        {{ item.name }}
        <ul>
          <li v-for="subItem in item.subItems" :key="subItem.id">
            {{ subItem.name }}
          </li>
        </ul>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [
        {
          id: 1,
          name: 'Item 1',
          subItems: [
            { id: 1, name: 'Sub Item 1' },
            { id: 2, name: 'Sub Item 2' },
          ],
        },
        {
          id: 2,
          name: 'Item 2',
          subItems: [
            { id: 3, name: 'Sub Item 3' },
            { id: 4, name: 'Sub Item 4' },
          ],
        },
      ],
    };
  },
};
</script>
