Vue プロジェクトでマルチレベル メニューの動的な表示と選択を実装する方法

menuData: [
  {
    name: '首页',
    path: '/home',
    items: []
  },
  {
    name: '关于我们',
    path: '/about',
    items: []
  },
  {
    name: '产品',
    path: '/products',
    items: [
      {
        name: '产品1',
        path: '/products/product1',
        items: []
      },
      {
        name: '产品2',
        path: '/products/product2',
        items: []
      }
    ]
  }
]

<template>
  <ul>
    <li v-for="menu in menuData" :key="menu.path">
      <router-link :to="menu.path" :class="{ active: isActive(menu) }">{{ menu.name }}</router-link>
      <menu v-if="menu.items.length" :menu-data="menu.items"></menu>
    </li>
  </ul>
</template>

<script>
export default {
  props: {
    menuData: {
      type: Array,
      required: true
    }
  },
  methods: {
    isActive(menu) {
      return this.$route.path === menu.path
    }
  }
}
