# 穿梭列表

- 页面: https://jiguang132.com/zh/resources/material-ui/docs/transfer-list
- 资源: Material UI (https://jiguang132.com/zh/resources/material-ui.md)
- 全部指南: https://jiguang132.com/zh/resources/material-ui/docs.md

组合左右列表、选择状态和移动操作。

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

这是 Core 原语的组合，不存在单独 TransferList 导出；集合、移动规则和持久化由宿主负责。

## 原生组成与范围

`List`, `ListItem`, `Checkbox`, `Switch`

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 |
| --- | --- | --- |
| `List.dense` | 原生紧凑布局，仍须保留可读性与触控目标。 | `List` |
| `Checkbox.checked` | 受控二元选择，与原生变化回调配套。 | `Checkbox` |
| `Checkbox.indeterminate` | 汇总项部分选中的视觉状态，与 checked 分开。 | `Checkbox` |

## 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。

## 真实使用示例

固定版本的未修改原生示例；复制时同时保留所需的局部辅助文件。

## 示例依赖边界

`react`, `@mui/material/Grid`, `@mui/material/ListItemIcon`, `@mui/material/ListItemText`, `@mui/material/Checkbox`, `@mui/material/Button`, `@mui/material/Paper`, `@mui/material/Stack`, `@mui/material/MenuItem`, `@mui/material/MenuList`, `@mui/material/Card`, `@mui/material/CardHeader`, `@mui/material/Divider`

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。

## 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。
