Install: `npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1`

## Version and compatibility

Pinned Mantine Core 9.7.1 requires React and React DOM `^19.2.0` and matching `@mantine/hooks@9.7.1`, from the installed npm package's peerDependencies. Do not force it into React 18 or another incompatible version. Explain upgrade impact and agree on a plan with the project owner; do not hide conflicts with --force/--legacy-peer-deps. The native Provider enables `theme.respectReducedMotion` and uses `forceColorScheme` for light/dark.

## Use case

Switch between mutually exclusive panels.

## Native props used by this example

These props are extracted from the local typechecked JSX and grouped by their owning native component. This is not an exhaustive prop list; see pinned source signatures and inheritance below.

| Component prop | Explanation |
| --- | --- |
| `Tabs.defaultValue` | Initial uncontrolled value, not a live controlled update. |
| `Tabs.Tab.value` | Controlled value; the native type defines its shape. |
| `Tabs.Panel.value` | Controlled value; the native type defines its shape. |
| `Tabs.Panel.pt` | Mantine top-padding style prop. |

## Interaction and state checks

Current scenarios: Default. Check actual behavior after selecting supported disabled/error/read-only scenarios; components without those native states do not receive invented universal props. Verify keyboard focus and exits, then connect changed values through the native callback signature.

## Business integration boundary

Demo content/state is local, without server persistence, authorization or fetching. A static display component is not a completed business workflow.

## Host setup

Install pinned @mantine/core and @mantine/hooks, import @mantine/core/styles.css at the entry and use MantineProvider. The example's theme/variant are JGuang-authored host props, not universal native component APIs; forceColorScheme synchronizes the app theme. Native implementation source is a reading reference: use npm exports rather than copying internal engines. This batch covers Core, not dates/charts/forms extension packages. Detailed upstream prose remains English.


## Runnable usage

```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>;
}

```


## Preview states

Default

The example uses the native Mantine API. For supported input demos, change the local variant to Disabled, Invalid or Read only; these are example labels, not new component props. Keep the documented data, controlled values, stores and compound children when adapting the example.



## 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>
  );
}
```
