Wordpress WP API V2的Nuxt/Vue导航菜单问题

我正在用Nuxt和无头wordpress建立一个网站。所有数据都来自WordPressAPI（wp json）

我对导航菜单、父/子菜单项有问题

单击父元素时，会立即触发每个包含子元素的菜单项。 我只需要它来触发我点击的那个

以下是我到目前为止的情况：

HTML:

<nav>
    <div class="">
      <!-- Triggers burger menu -->
      <ul :class="isOpen ? 'block' : 'hidden'" class="sm:flex">
        <!-- Loop through the parent navigation -->
        <!-- Add click event to trigger dropdown menu -->
        <li class="sm:mx-8 text-white cursor-pointer py-4 sm:py-0" 
            v-for="item in linksArray" 
            :key="item.ID"
            @click="isOpen = !isOpen"
        >
          <!-- Insert the data from wp-json -->
          <div class="">
            <!-- Parent navigation elements -->
            <div class="flex items-center">
              <div class=""> {{item.title}} </div>
            </div>
            <!-- Child navigation here -->
            <div>
              <!-- Trigger show or hide child elements on click from above -->
              <ul 
              v-show="isOpen" 
              class="sm:absolute bg-gray-800 rounded mt-4"
              >
                <!-- Loop through the child elements -->
                <li class="text-white rounded hover:bg-gray-700 cursor-pointer py-2 px-2"
                    v-for="childItem in item.child_items" 
                    :key="childItem.ID"
                >
                  <!-- Insert the data for children from wp-json -->
                  <nuxt-link :to="childItem.url">
                    <div class="flex items-center">
                      <span class="title">
                        {{ childItem.title }}
                      </span>
                    </div>
                  </nuxt-link>

                </li>
              </ul>
            </div>
          </div>
        </li>
      </ul>
    </div>
  </nav>

<script>
  export default {
    name: "Navbar",
    props: {
      linksArray: {
        type: Array
      },
    },
    data() {
      return {
        isOpen: false,
      };
    },
    watch: {
      // Use to close the menu on route change
      '$route'() {
        this.isOpen = false;
      },
    }
  };
</script>

我是新来的开发人员，现在已经在这上面呆了一个多星期了。 不知道去哪里寻找答案。在这里或谷歌上找不到任何东西。 你能告诉我我做错了什么或者解决方法吗

谢谢

在您的代码中，所有子项都使用相同的变量来表示是否应显示它们。因此，如果此变量为true，则会显示所有子项，如果为false，则会隐藏所有子项

您需要跟踪要显示的菜单项。以下是您如何实现这一目标的示例：

newvue({
el:“应用程序”，
数据：{
菜单：[{
标题：“主要的一个”，
儿童：['儿童1'，儿童2'，儿童3']
},
{
标题:"主二",，
儿童：[‘儿童4’、‘儿童5’、‘儿童6’]
},
{
标题:"主三",，
儿童：[“儿童7”]
},
{
标题:"主四",，
儿童：[“儿童8”，“儿童9']
}
],
openMenu:空
},
方法：{
表演儿童（一）{
如果（this.openMenu==i）this.openMenu=null
否则此.openMenu=i
}
}
})

li{
利润率：8px；
填充：8px；
背景：粉红色；
光标：指针；
}

菜单：


{{nav.title}

{{child}}

非常感谢Nate！我想了想，但不知道如何实施。现在它有意义了。一切都很好！乐意帮忙：-）
