# Transfer List

- Page: https://jiguang132.com/resources/material-ui/docs/transfer-list
- Resource: Material UI (https://jiguang132.com/resources/material-ui.md)
- All guides: https://jiguang132.com/resources/material-ui/docs.md

Compose two lists with selection and move controls.

This guide covers Material UI Core with the default Emotion engine; extensions and additional demos are explicitly classified.

## Use case and business boundary

This is an authored composition of Core primitives, not one TransferList export; the host owns sets, move rules and persistence.

## Native composition and scope

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

Preserve native Material UI composition and types; do not substitute JGuang UI/Base UI/Radix APIs. Example entries are not extra components.

## Native installation and initialization

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

Use native npm and Emotion, not an invented JGuang UI Registry URL. Place examples inside native ThemeProvider; choose CssBaseline or ScopedCssBaseline for the project. Inspect React, existing providers, lockfile and SSR first. Never overwrite files or conceal peer conflicts. This batch verified React 19.2.8; React 18 and below require matching react-is. See the included bilingual setup guide.

## Practical native parameters

These selected parameters are not a flattened universal API. Preserve the native declaring owner, slot structure, nullable values and generics.

| Owner.prop | Practical role | Declaration source |
| --- | --- | --- |
| `List.dense` | Native compact layout; preserve readability and touch targets. | `List` |
| `Checkbox.checked` | Controlled binary selection; pair with the native change callback. | `Checkbox` |
| `Checkbox.indeterminate` | Visual aggregate partial selection, separate from checked. | `Checkbox` |

## Runnable native examples

Machine keys select example entries, not universal variant props. Native demo JSX/data stay unchanged; JGuang-authored acceptance fixtures are explicitly labelled.

- Basic transfer list · `TransferList` · upstream native demo
- Enhanced transfer list · `SelectAllTransferList` · upstream native demo

## Actual usage example

Unmodified pinned native demo; copy its required local helper files together.

## Example dependency boundaries

`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`

Direct Icons/System/Utils example imports require their matching 9.4.0 packages. Relative data/helpers are part of the example closure, not extra components. Remote images and simulated operations do not supply a backend.

## Pinned upstream API metadata reference

These tables retain the upstream metadata, not a newly inferred generic type system. Conditional generics, inherited props and callback details are defined by the source declarations below. Theme defaults may override metadata defaults.

### List

```tsx
import List from '@mui/material/List';
import { List } from '@mui/material';
```

| Prop | Required | Upstream metadata type / constraint | Metadata default |
| --- | --- | --- | --- |
| `children` | no | `node` | — |
| `classes` | no | `object` | — |
| `component` | no | `elementType` | — |
| `dense` | no | `bool` | `false` |
| `disablePadding` | no | `bool` | `false` |
| `subheader` | no | `node` | — |
| `sx` | no | `Array<func \| object \| bool> \| func \| object` | — |



### ListItem

```tsx
import ListItem from '@mui/material/ListItem';
import { ListItem } from '@mui/material';
```

| Prop | Required | Upstream metadata type / constraint | Metadata default |
| --- | --- | --- | --- |
| `alignItems` | no | `'center' \| 'flex-start'` | `'center'` |
| `children` | no | `node` | — |
| `classes` | no | `object` | — |
| `component` | no | `elementType` | — |

| `disableGutters` | no | `bool` | `false` |
| `disablePadding` | no | `bool` | `false` |
| `divider` | no | `bool` | `false` |
| `secondaryAction` | no | `node` | — |
| `slotProps` | no | `{ root?: func \| object, secondaryAction?: func \| object }` | `{}` |
| `slots` | no | `{ root?: elementType, secondaryAction?: elementType }` | `{}` |
| `sx` | no | `Array<func \| object \| bool> \| func \| object` | — |



### Checkbox

```tsx
import Checkbox from '@mui/material/Checkbox';
import { Checkbox } from '@mui/material';
```

Native inheritance: `ButtonBase`. Parent/DOM props are not fabricated as additional own props.

| Prop | Required | Upstream metadata type / constraint | Metadata default |
| --- | --- | --- | --- |
| `checked` | no | `bool` | — |
| `checkedIcon` | no | `node` | `<CheckBoxIcon />` |
| `classes` | no | `object` | — |
| `color` | no | `'default' \| 'primary' \| 'secondary' \| 'error' \| 'info' \| 'success' \| 'warning' \| string` | `'primary'` |
| `defaultChecked` | no | `bool` | — |
| `disabled` | no | `bool` | `false` |
| `disableRipple` | no | `bool` | `false` |
| `icon` | no | `node` | `<CheckBoxOutlineBlankIcon />` |
| `id` | no | `string` | — |
| `indeterminate` | no | `bool` | `false` |
| `indeterminateIcon` | no | `node` | `<IndeterminateCheckBoxIcon />` |
| `onChange` | no | `func` | — |
| `required` | no | `bool` | `false` |
| `size` | no | `'medium' \| 'small' \| string` | `'medium'` |
| `slotProps` | no | `{ input?: func \| object, root?: func \| object }` | `{}` |
| `slots` | no | `{ input?: elementType, root?: elementType }` | `{}` |
| `sx` | no | `Array<func \| object \| bool> \| func \| object` | — |
| `value` | no | `any` | — |



### Switch

```tsx
import Switch from '@mui/material/Switch';
import { Switch } from '@mui/material';
```

Native inheritance: `IconButton`. Parent/DOM props are not fabricated as additional own props.

| Prop | Required | Upstream metadata type / constraint | Metadata default |
| --- | --- | --- | --- |
| `checked` | no | `bool` | — |
| `checkedIcon` | no | `node` | — |
| `classes` | no | `object` | — |
| `color` | no | `'default' \| 'primary' \| 'secondary' \| 'error' \| 'info' \| 'success' \| 'warning' \| string` | `'primary'` |
| `defaultChecked` | no | `bool` | — |
| `disabled` | no | `bool` | — |
| `disableRipple` | no | `bool` | `false` |
| `edge` | no | `'end' \| 'start' \| false` | `false` |
| `icon` | no | `node` | — |
| `id` | no | `string` | — |
| `onChange` | no | `func` | — |
| `required` | no | `bool` | `false` |
| `size` | no | `'medium' \| 'small' \| string` | `'medium'` |
| `slotProps` | no | `{ input?: func \| object, root?: func \| object, switchBase?: func \| object, thumb?: func \| object, track?: func \| object }` | `{}` |
| `slots` | no | `{ input?: elementType, root?: elementType, switchBase?: elementType, thumb?: elementType, track?: elementType }` | `{}` |
| `sx` | no | `Array<func \| object \| bool> \| func \| object` | — |
| `value` | no | `any` | — |


## Native source declarations

Declarations/imports are extracted from pinned source without flattening unions or external inheritance. Original English comments/types are source reference, not a claim of translated upstream prose. Shared types stay in their native packages.

## Post-install acceptance

Run strict types, production build and real interactions. Check keyboard labels/focus, disabled/error/read-only semantics where natively supported, both themes, narrow screens and reduced motion. Verify callbacks against the real host data; do not declare installation complete from copying a prompt. Initialization fixtures also require server HTML and warning-free hydration.
