- 资源: Mantine Core (https://jiguang132.com/zh/resources/mantine.md)
- 全部指南: https://jiguang132.com/zh/resources/mantine/docs.md

Mantine Core 的独立组件，请不要替换为 JGuang UI/Base UI 的同名 API。

## 安装

```bash
npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1
```

入口引入 `@mantine/core/styles.css`，并在根组件使用 `MantineProvider`；通过 `forceColorScheme` 同步深浅色主题。

## 使用与验证

在左侧选择组件，在预览中操作它的状态；使用“查看代码”检查真实源码。安装后执行类型检查和构建，再验证键盘焦点、手机布局与深浅色主题。

## 版本与兼容性

固定的 Mantine Core 9.7.1 要求 React 和 React DOM 满足 `^19.2.0`，并配套 `@mantine/hooks@9.7.1`。此条件来自实际 npm 包的 peerDependencies。React 18 或其他不兼容版本不能强行安装；先向项目负责人说明升级影响并确认方案，不使用 --force/--legacy-peer-deps 掩盖冲突。入口的原生 Provider 开启 `theme.respectReducedMotion`，并用 `forceColorScheme` 控制深浅色。

## 适用场景

在互斥选项组中选择一个值。

## 本地示例使用的原生参数

以下参数由本地、经过类型检查的 JSX 示例提取，按所属组件区分。不是全部属性清单；完整签名和继承关系见下方固定源码参考。

| 组件参数 | 说明 |
| --- | --- |
| `Radio.Group.defaultValue` | 非受控初始值，不是持续更新的受控值。 |
| `Radio.disabled` | 禁用用户输入或操作，不等同于只读。 |
| `Radio.value` | 受控值，具体结构由原生类型定义。 |
| `Radio.label` | 可见标签或当前组件的标签内容。 |

## 交互与状态检查

当前场景：默认、禁用。切换支持的禁用、错误或只读场景后检查真实行为；无此原生状态的组件不会被强行添加统一属性。验证键盘焦点和退出方式，修改值后按原生回调签名连接业务状态。

## 业务接入边界

由 Radio.Group 管理 value/onChange，每个子 Radio 需要独立 value；不要把布尔值作为组选择值。

## 宿主配置

先安装固定版本 @mantine/core 和 @mantine/hooks，在入口引入 @mantine/core/styles.css，并使用 MantineProvider。示例的 theme 和 variant 是 JGuang 编写的宿主参数，不是所有原生组件都接受的统一 API；通过 forceColorScheme 同步应用主题。源码面板中的原生实现仅供阅读，使用 npm 导出，不要单独复制内部实现。此批只覆盖 Core，不包括日期、图表和表单扩展包。上游详细说明保留英文，不宣称全文中文化。


## 可运行用法

以下代码使用资源原生 API；不是把其他设计系统的同名组件替换进来。

```tsx
import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {
const [value, setValue] = useState(35);
const disabled = variant === "Disabled";
return <M.Radio.Group defaultValue="react"><M.Group><M.Radio disabled={disabled} value="react" label="React" /><M.Radio disabled={disabled} value="vue" label="Vue" /></M.Group></M.Radio.Group>;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

```


## 可用状态与示例

默认、禁用

示例遵循 Mantine 原生 API。支持多状态的输入组件可将示例中的 variant 改为 Disabled、Invalid 或 Read only；这些只是示例标签，不是新增的组件属性。改造时保留组件要求的数据、受控值、store 和复合子组件结构。


## Usage



## Controlled

```tsx
import { useState } from 'react';
import { Radio } from '@mantine/core';

function Demo() {
  const [checked, setChecked] = useState(false);
  return (
    <Radio
      checked={checked}
      onChange={(event) => setChecked(event.currentTarget.checked)}
    />
  );
}
```

## Uncontrolled

`Radio` can be used with uncontrolled forms the same way as a native `input[type="radio"]`.
Set the `name` and `value` attributes to include radio value in `FormData` object on form submission.
To control the initial checked state in uncontrolled forms, use `defaultChecked` prop.

Example usage of uncontrolled `Radio` with `FormData`:

```tsx
import { Radio } from '@mantine/core';

function Demo() {
  return (
    <form
      onSubmit={(event) => {
        event.preventDefault();
        const formData = new FormData(event.currentTarget);
        console.log('Radio value:', formData.get('option'));
      }}
    >
      <Radio name="option" value="option1" label="Option 1" />
      <Radio name="option" value="option2" label="Option 2" defaultChecked />
      <button type="submit">Submit</button>
    </form>
  );
}
```

## States



## Light variant

`Radio` supports `filled` (default), `outline` and `light` variants. With `variant="light"`, the checked state has a light background and a contrasting icon. Colors of the `light` variant are resolved with [theme.variantColorResolver](/theming/colors#colors-variant-resolver), the same way as in [Button](/core/button/) – `color` can be a key of `theme.colors` or any valid CSS color:



## Change icon



## Change icon color



## Disabled state



## Pointer cursor

By default, the radio input and label have `cursor: default` (same as native `input[type="radio"]`).
To change the cursor to pointer, set `cursorType` on the [theme](/theming/theme-object/):

```tsx
import { createTheme, MantineProvider, Radio } from '@mantine/core';

const theme = createTheme({
  cursorType: 'pointer',
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      <Radio label="Pointer cursor" />
    </MantineProvider>
  );
}
```

## Radio with tooltip

You can change the target element to which the tooltip is attached with `refProp`:

- If `refProp` is not set, the tooltip is attached to the radio input
- If `refProp="rootRef"` is set, the tooltip is attached to the root element (contains label, input, and other elements)




## Radio.Group component



## Radio.Group disabled state



## Controlled Radio.Group

```tsx
import { useState } from 'react';
import { Radio } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState('react');

  return (
    <Radio.Group
      value={value}
      onChange={setValue}
      name="favoriteFramework"
      label="Select your favorite framework/library"
      description="This is anonymous"
      withAsterisk
    >
      <Radio value="react" label="React" />
      <Radio value="svelte" label="Svelte" />
      <Radio value="ng" label="Angular" />
      <Radio value="vue" label="Vue" />
    </Radio.Group>
  );
}
```

## Radio.Indicator

`Radio.Indicator` looks exactly the same as the `Radio` component, but it does not
have any semantic meaning; it's just a visual representation of the radio state. You
can use it in any place where you need to display the radio state without any interaction
related to the indicator. For example, it is useful in cards based on buttons, trees, etc.

Note that `Radio.Indicator` cannot be focused or selected with the keyboard. It is not
accessible and should not be used as a replacement for the `Radio` component.

`Radio.Indicator` supports the same `variant` values as `Radio`: `filled`, `outline` and `light`.



## Radio.Card component

`Radio.Card` component can be used as a replacement for `Radio` to build custom
cards/buttons/other things that work as radios. The root element of the component
has the `role="radio"` attribute; it is accessible by default and supports the same
keyboard interactions as `input[type="radio"]`.



You can use `Radio.Card` with `Radio.Group` the same way as the `Radio` component:







## Accessibility

Set the `aria-label` or `label` prop to make the radio accessible:

```tsx
import { Radio } from '@mantine/core';

// Not ok, input is not labeled
function Bad() {
  return <Radio />;
}

// Ok, input is labeled by aria-label
function GoodAriaLabel() {
  return <Radio aria-label="My radio" />;
}

// Ok, input is labeled by label element
function GoodLabel() {
  return <Radio label="My radio" />;
}
```


## 源码参数参考

以下实现签名和类型从本地固定版本源码生成。保留可选属性、原生继承类型、联合分支和 never 限制；不会将其他设计系统的 API 混入。forwardRef 实现中的 ref 属于 React 引用，不是新增业务属性。此区域是原始类型参考，不是上游说明的全文翻译。
