在当前页面展开和收起相关详情。

本指南覆盖默认 Emotion 环境的 Material UI Core；扩展包与额外示例按清单单独标注。

## 使用场景与业务边界

展开是界面状态，不代表已加载后端数据；保留标题层级与无障碍关联。

## 原生组成与范围

`Accordion`, `AccordionActions`, `AccordionDetails`, `AccordionSummary`

保持 Material UI 原生组合与类型，不替换为 JGuang／Base UI／Radix 同名 API。示例条目不是额外组件。

## 原生安装与初始化

```bash
npm install @mui/material@9.4.0 @emotion/react@11.14.0 @emotion/styled@11.14.1
```

采用原生 npm 包与 Emotion，不提供虚构的 JGuang UI Registry 地址。将示例放在原生 ThemeProvider 内，按项目选择 CssBaseline 或 ScopedCssBaseline。先检查 React、现有 Provider、锁文件与 SSR 配置；不要覆盖用户文件或忽略 peer 冲突。本批实际验收 React 19.2.8；React 18 及以下须匹配 react-is。完整初始化规则见随附的双语 setup 文档。

## 关键原生参数

仅解释本指南选出的关键参数，不是平铺的通用 API。原生继承来源、slot 结构、可空值与泛型仍按固定源码保留。

| 所属组件.属性 | 用途说明 | 声明来源 |
| --- | --- | --- |
| `Accordion.expanded` | 受控 Accordion 展开状态，在 onChange 中更新。 | `Accordion` |
| `Accordion.onChange` | 所属控件的原生回调，保留其准确事件／数值／可空签名。 | `Accordion` |
| `Accordion.defaultExpanded` | 非受控 Accordion 的初始展开值，不是持续受控值。 | `Accordion` |
| `Accordion.disabled` | 原生禁用交互状态，不是权限校验。 | `Accordion` |

## 可运行原生示例

下列机器键只选择示例入口，不会作为通用 variant 属性传入每个组件。原生示例 JSX 与数据保持上游原文；JGuang 编写的验收示例明确标注。

```tsx
import * as React from 'react';
import Accordion from '@mui/material/Accordion';
import AccordionActions from '@mui/material/AccordionActions';
import AccordionSummary from '@mui/material/AccordionSummary';
import AccordionDetails from '@mui/material/AccordionDetails';
import Typography from '@mui/material/Typography';
import ExpandMoreIcon from '@mui/icons-material/ExpandMore';
import Button from '@mui/material/Button';

export default function AccordionUsage() {
  const id = React.useId();
  return (
    <div>
      <Accordion>
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls={`${id}-panel1-content`}
          id={`${id}-panel1-header`}
        >
          <Typography component="span">Accordion 1</Typography>
        </AccordionSummary>
        <AccordionDetails>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse
          malesuada lacus ex, sit amet blandit leo lobortis eget.
        </AccordionDetails>
      </Accordion>
      <Accordion>
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls={`${id}-panel2-content`}
          id={`${id}-panel2-header`}
        >
          <Typography component="span">Accordion 2</Typography>
        </AccordionSummary>
        <AccordionDetails>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse
          malesuada lacus ex, sit amet blandit leo lobortis eget.
        </AccordionDetails>
      </Accordion>
      <Accordion defaultExpanded>
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls={`${id}-panel3-content`}
          id={`${id}-panel3-header`}
        >
          <Typography component="span">Accordion Actions</Typography>
        </AccordionSummary>
        <AccordionDetails>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse
          malesuada lacus ex, sit amet blandit leo lobortis eget.
        </AccordionDetails>
        <AccordionActions>
          <Button>Cancel</Button>
          <Button>Agree</Button>
        </AccordionActions>
      </Accordion>
    </div>
  );
}

```

## 示例依赖边界

`react`, `@mui/material/Accordion`, `@mui/material/AccordionActions`, `@mui/material/AccordionSummary`, `@mui/material/AccordionDetails`, `@mui/material/Typography`, `@mui/icons-material/ExpandMore`, `@mui/material/Button`, `@mui/icons-material/ArrowDownward`, `@mui/icons-material/ArrowDropDown`, `@mui/material/Fade`, `@mui/material/styles`, `@mui/icons-material/ArrowForwardIosSharp`

直接导入 Icons／System／Utils 的示例需要匹配 9.4.0 包。局部数据与辅助文件属于示例闭包，不是额外组件。远程图片和模拟操作不提供后端。

## 固定上游 API 元数据参考

以下表格保留上游元数据，不是重新推断的通用类型体系。条件泛型、继承属性与回调细节以以下源码声明为准。主题默认配置可能覆盖元数据默认值。

## 原生源码声明

声明与 import 从固定源码提取，不平铺联合类型或外部继承。英文注释／类型属于原始源码参考，不代表上游正文已全文翻译。共享类型仍位于原生包中。

## 安装后验收

执行严格类型检查、生产构建和实际交互。检查键盘标签／焦点、原生支持的禁用／错误／只读语义、深浅色、窄屏和减少动画。按真实宿主数据检查回调，不把复制提示词当作安装完成。初始化工具还需检查服务端 HTML 与无告警水合。
