Basic Usage

Use v-model to control the name of active panels

<van-collapse v-model="activeNames">
  <van-collapse-item title="Title1" name="1">Content</van-collapse-item>
  <van-collapse-item title="Title2" name="2">Content</van-collapse-item>
  <van-collapse-item title="Title3" name="3" disabled>Content</van-collapse-item>
</van-collapse>

export default {
  data() {
    return {
      activeNames: ['1']
    };
  }
};

</van-collapse>

export default {
  data() {
    return {
      activeName: '1'
    };
  }
};
