- 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

用可折叠分区展示相关内容。

## 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 |
| --- | --- |
| `Accordion.style` | 本地样式或布局对象。 |
| `Accordion.defaultValue` | 非受控初始值，不是持续更新的受控值。 |
| `Accordion.Item.value` | 受控值，具体结构由原生类型定义。 |

## 交互与状态检查

当前场景：默认。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

示例内容和状态仅保存在本地，不提供服务端持久化、授权或数据请求。静态展示组件不应被当作已完成的业务流程。

## 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 content = <M.Text>Build something beautiful / 构建美好的界面</M.Text>;
return <M.Accordion style={{ width: 360 }} defaultValue="design"><M.Accordion.Item value="design"><M.Accordion.Control>Design system / 设计系统</M.Accordion.Control><M.Accordion.Panel>{content}</M.Accordion.Panel></M.Accordion.Item></M.Accordion>;
}
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

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

Accordion allows users to expand and collapse sections of content.
It helps manage large amounts of information in a limited space
by showing only section headers initially and revealing content upon interaction.

Accordion is commonly used for:
- FAQ sections: displaying questions as headers with answers revealed when clicked
- Forms: organizing long forms into sections, for example, personal info, shipping, and payment
- Menus: nested navigation in sidebars or mobile views



## order prop

The `order` prop (used in all demos on this page) sets the heading level for the `Accordion.Control` root element.
According to [WAI-ARIA recommendations](https://www.w3.org/WAI/ARIA/apg/patterns/accordion/),
it is required to use `h2`-`h6` heading levels to fit correctly within the outline of the page.

All examples on this page use `order={3}`, which means that all `button` elements of
`Accordion.Control` are wrapped with an `h3` tag (`h2` tags are used for the documentation sections).

The `order` prop is not enforced by the library but is required if your application
must meet accessibility standards.

## Change chevron

Use the `chevron` prop to change the chevron icon. When `chevron` is set,
the `chevronIconSize` prop is ignored. To remove the chevron icon, use `chevron={null}`.

To customize chevron styles, use [Styles API](/styles/styles-api/) with the
[data-rotate](/styles/data-attributes/) attribute. This attribute is set when the item
is opened if the `disableChevronRotation` prop is not set.

Example of a custom chevron icon with rotation styles:



## Custom control label

You can use any React node as a label for `Accordion.Control` component.
When you use nested elements in `Accordion.Control`, it is recommended to
set `aria-label` attribute to make the control accessible for screen readers.



## With icons

Use the `icon` prop to display any element in the left section of the `Accordion.Control`:



## Change transition

To change transition duration, set `transitionDuration` prop:



To disable transitions, set `transitionDuration` to 0:



## Default opened items

For `multiple={false}`, set `defaultValue` as string:

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

function Demo() {
  // Second item will be opened by default
  return (
    <Accordion defaultValue="item-2">
      <Accordion.Item value="item-1">{/* item-1 */}</Accordion.Item>
      <Accordion.Item value="item-2">{/* item-2 */}</Accordion.Item>
    </Accordion>
  );
}
```

For `multiple={true}`, set `defaultValue` as an array of strings:

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

function Demo() {
  // Both items are opened by default
  return (
    <Accordion multiple defaultValue={['item-1', 'item-2']}>
      <Accordion.Item value="item-1">{/* item-1 */}</Accordion.Item>
      <Accordion.Item value="item-2">{/* item-2 */}</Accordion.Item>
    </Accordion>
  );
}
```

## Control opened state

For `multiple={false}`, set `value` as string:

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

function Demo() {
  const [value, setValue] = useState<string | null>(null);

  return (
    <Accordion value={value} onChange={setValue}>
      <Accordion.Item value="item-1">{/* item-1 */}</Accordion.Item>
      <Accordion.Item value="item-2">{/* item-2 */}</Accordion.Item>
    </Accordion>
  );
}
```

For `multiple={true}`, set `value` as an array of strings:

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

function Demo() {
  const [value, setValue] = useState<string[]>([]);

  return (
    <Accordion multiple value={value} onChange={setValue}>
      <Accordion.Item value="item-1">{/* item-1 */}</Accordion.Item>
      <Accordion.Item value="item-2">{/* item-2 */}</Accordion.Item>
    </Accordion>
  );
}
```

## Disable collapse

By default, in single mode (`multiple={false}`) the open item can always be toggled closed,
which leaves the Accordion fully collapsed. Set the `disableCollapse` prop to prevent this:
once an item is open, clicking its control again is a no-op, and the only way to change state
is to open a different item. This is useful for settings panels, stepper-style flows and FAQ
pages where one section should always stay visible.

`disableCollapse` only prevents collapsing an already-open item – it does not force an item
open on mount. To guarantee that one item is open from the start, pair it with `defaultValue`
(uncontrolled) or `value` (controlled).

The prop has no effect when `multiple` is set, as multiple mode already allows any combination
of opened and closed items.



## Compose controls

Putting a button or link inside `Accordion.Control` is a common mistake when
using Accordion. The `Accordion.Control` root element is a `button`. Putting interactive
elements inside other interactive elements is forbidden – you will receive a DOM
validation error from React if you try to implement the following component:

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

// ❌ Incorrect usage: do not do this
function Demo() {
  return (
    <Accordion.Item value="item-1">
      <Accordion.Control>
        <Group>
          <span>Control 1</span>
          <button>My action</button>
        </Group>
      </Accordion.Control>
      <Accordion.Panel>Panel 1</Accordion.Panel>
    </Accordion.Item>
  );
}
```

Instead of putting interactive elements inside the `Accordion.Control`, render them
next to it. For example, you can add an [ActionIcon](/core/action-icon/) or [Menu](/core/menu/)
to the right side of the original control. If you need to display an interactive element
over the `Accordion.Control`, use `position: absolute` instead.



## Disabled items

Set the `disabled` prop on the `Accordion.Control` component to disable it.
When you disable items, users cannot activate them with the mouse or keyboard,
and arrow key navigation will skip them:



## Unstyled Accordion

Set the `unstyled` prop on the Accordion component to remove all non-essential
library styles. Use the `unstyled` prop to style the component with the
[Styles API](/styles/styles-api/) without overriding any styles.






Example of using [Styles API](/styles/styles-api/) to customize Accordion styles:



## TypeScript

The `AccordionProps` type exported from `@mantine/core` is a generic that accepts a boolean type
describing the `multiple` state:

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

type MultipleAccordionProps = AccordionProps<true>;
type DefaultAccordionProps = AccordionProps<false>;
```

## Accessibility

The Accordion component implements the [WAI-ARIA accessibility pattern](https://www.w3.org/WAI/ARIA/apg/patterns/accordion/).
