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

Choose one value through adjacent segments.

## 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 |
| --- | --- |
| `SegmentedControl.data` | Local options/nodes; keep unique values and native schema. |

## 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';

const fruit = ["Apple", "Banana", "Orange"];
function ComponentPreview({ variant = 'Default' }: { variant?: string }) {

return <M.SegmentedControl data={fruit} />;
}
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

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

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

  return (
    <SegmentedControl
      value={value}
      onChange={setValue}
      data={[
        { label: 'React', value: 'react' },
        { label: 'Angular', value: 'ng' },
        { label: 'Vue', value: 'vue' },
        { label: 'Svelte', value: 'svelte' },
      ]}
    />
  );
}
```

## Uncontrolled

`SegmentedControl` can be used with uncontrolled forms the same way as a native input element.
Set the `name` attribute to include segmented control value in `FormData` object on form submission.
To control the initial value in uncontrolled forms, use the `defaultValue` prop.

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

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

function Demo() {
  return (
    <form
      onSubmit={(event) => {
        event.preventDefault();
        const formData = new FormData(event.currentTarget);
        console.log('Segmented control value:', formData.get('framework'));
      }}
    >
      <SegmentedControl
        name="framework"
        defaultValue="react"
        data={[
          { label: 'React', value: 'react' },
          { label: 'Angular', value: 'ng' },
          { label: 'Vue', value: 'vue' },
          { label: 'Svelte', value: 'svelte' },
        ]}
      />
      <button type="submit">Submit</button>
    </form>
  );
}
```

## Data prop

`SegmentedControl` supports two different data formats:

1. An array of primitive values – used when `value` and `label` are the same
2. An array of objects – used when `value` and `label` are different

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

function ArrayOfStrings() {
  return (
    <SegmentedControl data={['React', 'Angular', 'Svelte', 'Vue']} />
  );
}

function ArrayOfObjects() {
  return (
    <SegmentedControl
      data={[
        { value: 'React', label: 'React' },
        { value: 'Angular', label: 'Angular' },
        { value: 'Svelte', label: 'Svelte' },
        { value: 'Vue', label: 'Vue' },
      ]}
    />
  );
}
```

## Generic value type

`SegmentedControl` supports generic value type. You can pass primitive values (numbers, strings, boolean, null)
as the type argument. The generic type is used for `value`, `defaultValue`, `onChange` and `data` props.



Example with strings union:

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

function Demo() {
  return (
    <SegmentedControl<'orange' | 'grape' | 'apple'>
      data={[
        { value: 'orange', label: 'Orange' },
        { value: 'grape', label: 'Grape' },
        { value: 'apple', label: 'Apple' },
      ]}
    />
  );
}
```

## Disabled

To disable a `SegmentedControl` item, use the array of objects `data` format and set `disabled: true`
on the item that you want to disable. To disable the entire component, use the `disabled` prop.



## React node as label

You can use any React node as a label:



## Color

By default, `SegmentedControl` uses `theme.white` with shadow in the light color scheme and `var(--mantine-color-dark-6)` background color for the indicator.
Set the `color` prop to change the indicator `background-color`:



## Auto contrast

`SegmentedControl` supports `autoContrast` prop. If set to `true`, the label text color will automatically adjust
to ensure optimal contrast against the indicator background color:



## Transitions

Change transition properties with:

- `transitionDuration` – all transitions duration in ms, `200` by default
- `transitionTimingFunction` – all transitions timing function, `ease` by default



## readOnly

Set the `readOnly` prop to prevent the value from being changed:






## Accessibility and usability

`SegmentedControl` uses radio inputs under the hood, so it is accessible by default with no extra steps required if you have text in labels.
The component supports the same keyboard events as a regular radio group.

If you do not have text in labels (for example, when you want to use `SegmentedControl` with icons only),
use [VisuallyHidden](/core/visually-hidden) to make the component accessible:




## Source-backed parameter reference

Implementation signatures and types are generated from the pinned local source. Optional props, native inherited types, union branches and never exclusions are preserved. A forwardRef implementation's ref is a React reference, not an additional business prop.


```ts
SegmentedControl(_props)
```



```ts
export type SegmentedControlStylesNames =
  | 'root'
  | 'input'
  | 'label'
  | 'control'
  | 'indicator'

  className?: string | undefined;

  /** Inline style added to root component element, can subscribe to theme defined on MantineProvider */
  style?: MantineStyleProp;

  /** CSS variables defined on root component element */
  __vars?: CssVarsProp;

  /** `size` property passed down the HTML element */

  visibleFrom?: MantineBreakpoint;

  /** Determines whether component should be hidden in light color scheme with `display: none` */
  lightHidden?: boolean;

  /** Determines whether component should be hidden in dark color scheme with `display: none` */
  darkHidden?: boolean;

  /** Element modifiers transformed into `data-` attributes, for example, `{ 'data-size': 'xl' }`, falsy values are removed */
  mod?: BoxMod;
}

export type ElementProps<
  ElementType extends React.ElementType,
  PropsToOmit extends string = never,

export interface CSSProperties extends React.CSSProperties {

export type CssVariable = `--${string}`;

export type CssVariables<Variable extends string = CssVariable> = Partial<Record<Variable, string>>;

export type CssVars<Variable extends string = CssVariable> =

  | CssVars<Variable>[];

export type CssVarsProp<Variable extends string = CssVariable> =

  | CssVars<Variable>[];
```


### Native and external types

External types remain defined by React or native dependencies, not manually expanded into guessed props. The installed version's TypeScript definitions are authoritative.


```ts
Factory<{
  props: SegmentedControlProps;
  ref: HTMLDivElement;
  stylesNames: SegmentedControlStylesNames;
  vars: SegmentedControlCssVariables;
  signature: <Value extends Primitive = string>(
    props: SegmentedControlProps<Value>
  ) => React.JSX.Element | null;
}>
Primitive
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<SegmentedControlFactory>
React.ElementType
Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>
React.ComponentProps<ElementType>
ElementType
PropsToOmit
Value
React.ReactNode
MantineColor
MantineSize
MantineRadius
