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

安装

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。

来源

https://github.com/mantinedev/mantine/tree/f0e2bc6d28b0f0b8aaefb5b859937bf77f539df7 MIT 许可证；不包括付费内容。下方提供上游英文参考内容，中文使用指南已适配；上游详细参考暂保留英文。

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.ptMantine 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。

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:

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:

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:

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).

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

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>
  );
}

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.

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:

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>
  );
}

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:

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>
  );
}

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

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

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

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

// 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 (add the 'use client' directive at the top of the file).

// 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 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 on accessibility.

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 component:

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:

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>
  );
}
