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

切换互斥内容面板。

## 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 |
| --- | --- |
| `Tabs.defaultValue` | 非受控初始值，不是持续更新的受控值。 |
| `Tabs.Tab.value` | 受控值，具体结构由原生类型定义。 |
| `Tabs.Panel.value` | 受控值，具体结构由原生类型定义。 |
| `Tabs.Panel.pt` | Mantine 顶部内边距样式参数。 |

## 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.Tabs defaultValue="preview"><M.Tabs.List><M.Tabs.Tab value="preview">Preview</M.Tabs.Tab><M.Tabs.Tab value="code">Code</M.Tabs.Tab></M.Tabs.List><M.Tabs.Panel value="preview" pt="md">{content}</M.Tabs.Panel><M.Tabs.Panel value="code" pt="md"><M.Code>npm install @mantine/core</M.Code></M.Tabs.Panel></M.Tabs>;
}
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



## Controlled Tabs

To control the Tabs state, use `value` and `onChange` props:

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

function Demo() {
  const [activeTab, setActiveTab] = useState<string | null>('first');

  return (
    <Tabs value={activeTab} onChange={setActiveTab}>
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="second">Second tab</Tabs.Tab>
      </Tabs.List>

      <Tabs.Panel value="first">First panel</Tabs.Panel>
      <Tabs.Panel value="second">Second panel</Tabs.Panel>
    </Tabs>
  );
}
```

## Uncontrolled Tabs

If you do not need to subscribe to Tabs state changes, use `defaultValue`:

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

function Demo() {
  return (
    <Tabs defaultValue="first">
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="second">Second tab</Tabs.Tab>
      </Tabs.List>

      <Tabs.Panel value="first">First panel</Tabs.Panel>
      <Tabs.Panel value="second">Second panel</Tabs.Panel>
    </Tabs>
  );
}
```

## Change colors

To change the colors of all tabs, set `color` on the `Tabs` component; to change the color of an individual tab,
set `color` on `Tabs.Tab`.



## Tabs position



To display a tab on the opposite side, set `margin-left: auto` with the `ml="auto"` prop or with `className`:



## Inverted tabs

To make tabs inverted, place `Tabs.Panel` components before `Tabs.List` and add the `inverted` prop to the `Tabs` component:



## Vertical tabs placement

To change the placement of `Tabs.List` in vertical orientation, set the `placement` prop:



## Custom variants

Example of custom variant with [FloatingIndicator](/core/floating-indicator):



## Disabled tabs

Set the `disabled` prop on the `Tabs.Tab` component to disable a tab.
Disabled tabs cannot be activated with the mouse or keyboard, and they will be skipped when the user navigates with arrow keys:



## Activation mode

By default, tabs are activated when the user presses arrow keys or Home/End keys.
To disable that, set `activateTabWithKeyboard={false}` on the `Tabs` component:



## Tab deactivation

By default, the active tab cannot be deactivated. To allow that, set `allowTabDeactivation` on the `Tabs` component:



## Unmount inactive tabs

By default, inactive `Tabs.Panel` will stay mounted; to unmount inactive tabs, set `keepMounted={false}` on Tabs.
This is useful when you want to render components that impact performance inside `Tabs.Panel`. Note that
components that are rendered inside `Tabs.Panel` will reset their state on each mount (tab change).

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

// Second tab panel will be mounted only when the user activates the second tab
function Demo() {
  return (
    <Tabs keepMounted={false} defaultValue="first">
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="second">Second tab</Tabs.Tab>
      </Tabs.List>

      <Tabs.Panel value="first">First panel</Tabs.Panel>
      <Tabs.Panel value="second">Second panel</Tabs.Panel>
    </Tabs>
  );
}
```

## Get tab control ref

```tsx
import { useRef } from 'react';
import { Tabs } from '@mantine/core';

function Demo() {
  const secondTabRef = useRef<HTMLButtonElement>(null);

  return (
    <Tabs defaultValue="first">
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="Second" ref={secondTabRef}>
          Second tab
        </Tabs.Tab>
        <Tabs.Tab value="third">Third tab</Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

## Tab as a link

You can render `Tabs.Tab` as an `a` element by using the `renderRoot` prop. This gives you
native link behavior: right-click to open in a new tab, middle-click, and `href` for
crawlers and accessibility.

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

function Demo() {
  return (
    <Tabs defaultValue="home">
      <Tabs.List>
        <Tabs.Tab
          value="home"
          renderRoot={(props) => <a href="/home" {...props} />}
        >
          Home
        </Tabs.Tab>
        <Tabs.Tab
          value="about"
          renderRoot={(props) => <a href="/about" {...props} />}
        >
          About
        </Tabs.Tab>
        <Tabs.Tab
          value="contacts"
          renderRoot={(props) => <a href="/contacts" {...props} />}
        >
          Contacts
        </Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

You can also use the `component` prop to render tabs as links:

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

function Demo() {
  return (
    <Tabs defaultValue="home">
      <Tabs.List>
        <Tabs.Tab value="home" component="a" href="/home">
          Home
        </Tabs.Tab>
        <Tabs.Tab value="about" component="a" href="/about">
          About
        </Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

## Tab as a link with Next.js

Use the `renderRoot` prop to render `Tabs.Tab` as a Next.js `Link` component. The `renderRoot` prop
is required instead of `component` because Next.js `Link` is a generic component:

```tsx
import Link from 'next/link';
import { usePathname } from 'next/navigation';
import { Tabs } from '@mantine/core';

function Demo() {
  const pathname = usePathname();

  return (
    <Tabs value={pathname}>
      <Tabs.List>
        <Tabs.Tab
          value="/home"
          renderRoot={(props) => <Link href="/home" {...props} />}
        >
          Home
        </Tabs.Tab>
        <Tabs.Tab
          value="/about"
          renderRoot={(props) => <Link href="/about" {...props} />}
        >
          About
        </Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

## Tab as a link with React Router

Use the `renderRoot` prop to render `Tabs.Tab` as a React Router `NavLink` or `Link` component:

```tsx
import {
  Link,
  Route,
  useLocation,
} from 'react-router-dom';
import { Tabs } from '@mantine/core';

// Route: <Route path="/tabs/:tabValue" element={<Demo />} />

function Demo() {
  const location = useLocation();

  return (
    <Tabs value={location.pathname}>
      <Tabs.List>
        <Tabs.Tab
          value="/tabs/first"
          renderRoot={(props) => (
            <Link to="/tabs/first" {...props} />
          )}
        >
          First tab
        </Tabs.Tab>
        <Tabs.Tab
          value="/tabs/second"
          renderRoot={(props) => (
            <Link to="/tabs/second" {...props} />
          )}
        >
          Second tab
        </Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

## Usage with react-router

```tsx
<Route path="/tabs/:tabValue" element={<Demo />} />
```

```tsx
import { useNavigate, useParams } from 'react-router-dom';
import { Tabs } from '@mantine/core';

function Demo() {
  const navigate = useNavigate();
  const { tabValue } = useParams();

  return (
    <Tabs
      value={tabValue}
      onChange={(value) => navigate(`/tabs/${value}`)}
    >
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="second">Second tab</Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

## Usage with Next.js Pages Router

```tsx
// For file /tabs/[activeTab].tsx
import { useRouter } from 'next/router';
import { Tabs } from '@mantine/core';

function Demo() {
  const router = useRouter();

  return (
    <Tabs
      value={router.query.activeTab as string}
      onChange={(value) => router.push(`/tabs/${value}`)}
    >
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="second">Second tab</Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

## Usage with Next.js App Router

In the App Router, get the current tab value from the pathname with the `usePathname`
hook and change tabs with the router returned by `useRouter`. Both hooks are imported
from `next/navigation`. Note that components that use these hooks must be
[Client Components](https://nextjs.org/docs/app/building-your-application/rendering/client-components)
(add the `'use client'` directive at the top of the file).

```tsx
// For file /tabs/[activeTab]/page.tsx
'use client';

import { usePathname, useRouter } from 'next/navigation';
import { Tabs } from '@mantine/core';

function Demo() {
  const router = useRouter();
  const pathname = usePathname();
  const activeTab = pathname.split('/').pop();

  return (
    <Tabs
      value={activeTab}
      onChange={(value) => router.push(`/tabs/${value}`)}
    >
      <Tabs.List>
        <Tabs.Tab value="first">First tab</Tabs.Tab>
        <Tabs.Tab value="second">Second tab</Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```




Example of Styles API usage to customize tab styles:



## Example with Scroller component

Use [Scroller](/core/scroller) component to make the tabs list scrollable when there are too many tabs to fit in the available space:



## Accessibility

The Tabs component follows [WAI-ARIA recommendations](https://www.w3.org/TR/wai-aria-practices/examples/tabs/tabs-2/tabs.html) on accessibility.

### Tabs as links

When `Tabs.Tab` is rendered as a link (`<a>` tag), the `role="tab"` attribute overrides
the implicit link role. Screen readers will announce the element as a "tab", not a "link".
This is the expected behavior per the WAI-ARIA specification.

When using tabs as navigation links without `Tabs.Panel` components, the `aria-controls` attribute
on each tab references a panel element that does not exist in the DOM. This is a minor
accessibility consideration – most screen readers handle this gracefully.

If you use `Tabs.Tab` without text content, for example, only with an icon, then set `aria-label`
or use the [VisuallyHidden](/core/visually-hidden) component:

```tsx
import { CoinIcon } from '@phosphor-icons/react';
import { Tabs, VisuallyHidden } from '@mantine/core';

function Demo() {
  return (
    <Tabs defaultValue="chat">
      <Tabs.List>
        {/* aria-label is not required, tab is labelled by children */}
        <Tabs.Tab value="chat">Chat</Tabs.Tab>

        {/* aria-label is required, tab is not labelled by children */}
        <Tabs.Tab
          value="money"
          aria-label="Get money"
          leftSection={<CoinIcon size={14} />}
        />

        {/* You can use VisuallyHidden instead of aria-label */}
        <Tabs.Tab value="money" leftSection={<CoinIcon size={14} />}>
          <VisuallyHidden>Get money</VisuallyHidden>
        </Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```

To set the tabs list label, set `aria-label` on the `Tabs.List` component; it will be announced by screen reader:

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

function Demo() {
  return (
    <Tabs defaultValue="recent">
      {/* Tabs.List aria-label will be announced when tab is focused for the first time */}
      <Tabs.List aria-label="Chats">
        <Tabs.Tab value="recent">Most recent</Tabs.Tab>
        <Tabs.Tab value="recent">Unanswered</Tabs.Tab>
        <Tabs.Tab value="archived">Archived</Tabs.Tab>
      </Tabs.List>
    </Tabs>
  );
}
```
