# 可展开项

> 切换显示嵌套属性

使用可展开项在响应字段中显示或隐藏嵌套内容。它们在 API 文档中展示复杂对象的属性时尤其有用。

<ResponseField name="user" type="User Object">
  <Expandable title="properties">
    <ResponseField name="full_name" type="string">
      用户的全名
    </ResponseField>

    <ResponseField name="is_over_21" type="boolean">
      用户是否年满 21 岁
    </ResponseField>
  </Expandable>
</ResponseField>
