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

Edit a numeric angle with a circular control.

## 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 |
| --- | --- |
| `AngleSlider.value` | Controlled value; the native type defines its shape. |
| `AngleSlider.onChange` | Native value/event callback; preserve its actual signature. |

## 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);
return <M.AngleSlider value={value} onChange={setValue} />;
}
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

Use the `AngleSlider` component to pick an angle value between 0 and 360:



## Controlled

The `AngleSlider` value is a number between 0 and 360.

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

function Demo() {
  const [value, setValue] = useState(180);
  return <AngleSlider value={value} onChange={setValue} />;
}
```

## AngleSlider with uncontrolled forms

`AngleSlider` can be used with uncontrolled forms.
Set the `name` attribute to include slider value in `FormData` object on form submission.
To control initial value in uncontrolled forms, use `defaultValue` prop.

Props for usage with uncontrolled forms:
- `name` – name attribute passed to the hidden input
- `hiddenInputProps` – additional props passed to the hidden input

Example of uncontrolled `AngleSlider` with `FormData`:

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

export function WithFormData() {
  return (
    <form
      onSubmit={(event) => {
        event.preventDefault();
        const formData = new FormData(event.currentTarget);
        console.log('Checkbox group value:', formData.get('angle'));
      }}
    >
      <AngleSlider name="angle" defaultValue={120} />
      <button type="submit">Submit</button>
    </form>
  );
}
```

## formatLabel

Use the `formatLabel` prop to change the angle label format.
It accepts a function that takes the angle value and returns a React node:



## Marks

Set the `marks` prop to display marks on the slider.
A mark is an object with a value (required, number between 0 and 360) and label (optional, React node).
To restrict selection to marks only, set the `restrictToMarks` prop:



## onChangeEnd

The `onChangeEnd` callback fires when the user stops dragging the slider or changes its value with the keyboard.
Use it as a debounced callback to prevent frequent updates.



## disabled

The `disabled` prop disables the component and prevents user interaction:



## Accessibility

To make the component accessible for screen readers, set the `aria-label` prop:

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

function Demo() {
  return <AngleSlider aria-label="Gradient angle" />;
}
```

Keyboard interactions when the component is focused:


## Based on use-radial-move

`AngleSlider` is based on the [use-radial-move](/hooks/use-radial-move) hook.
You can build a custom radial slider using this hook if you need more control over the component's behavior.




## 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
AngleSlider(_props)
```



```ts
export type AngleSliderStylesNames = 'root' | 'thumb' | 'label' | 'marks' | 'mark';

export type AngleSliderCssVariables = {
  root: '--slider-size' | '--thumb-size';
};

export interface AngleSliderProps
  extends BoxProps, StylesApiProps<AngleSliderFactory>, ElementProps<'div', 'onChange'> {
  /** Step between values @default 1 */
  step?: number;

  /** Controlled component value */
  value?: number;

  /** Uncontrolled component default value */
  defaultValue?: number;

  /** Called on value change */
  onChange?: (value: number) => void;

  /** Called after the selection is finished */
  onChangeEnd?: (value: number) => void;

  /** Called in `onMouseDown` and `onTouchStart` */
  onScrubStart?: () => void;

  /** Called in `onMouseUp` and `onTouchEnd` */
  onScrubEnd?: () => void;

  /** If set, the label is displayed inside the slider @default true */
  withLabel?: boolean;

  /** Array of marks displayed on the slider */

  /** Size of the thumb in px. Calculated based on the `size` value by default. */
  thumbSize?: number;

  /** A function to format label based on the current value */
  formatLabel?: (value: number) => React.ReactNode;

  /** Sets `data-disabled` attribute, disables interactions */
  disabled?: boolean;

  /** If set, the selection is allowed only from the given marks array @default false */
  restrictToMarks?: boolean;

  /** Props passed down to the hidden input */
  hiddenInputProps?: React.ComponentProps<'input'>;

  /** Hidden input name, use with uncontrolled component */
  name?: string;
}

export type AngleSliderFactory = Factory<{
  props: AngleSliderProps;
  ref: HTMLDivElement;
  stylesNames: AngleSliderStylesNames;
  vars: AngleSliderCssVariables;
}>;

export type Mod = Record<string, any> | string;

export type BoxMod = Mod | Mod[] | BoxMod[];

export interface BoxProps extends MantineStyleProps {
  /** Class added to the root element, if applicable */
  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 */
  __size?: string;

  /** Breakpoint above which the component is hidden with `display: none` */
  hiddenFrom?: MantineBreakpoint;

  /** Breakpoint below which the component is hidden with `display: none` */
  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,
> = Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>;

export interface CSSProperties extends React.CSSProperties {
  [key: string]: any;
}

type MantineStyle = CSSProperties | ((theme: MantineTheme) => CSSProperties);

export type MantineStyleProp = MantineStyle | MantineStyle[] | MantineStyleProp[] | undefined;

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

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

export type CssVars<Variable extends string = CssVariable> =
  | CssVariables<Variable>
  | ((theme: MantineTheme) => CssVariables<Variable>)
  | CssVars<Variable>[];

export type CssVarsProp<Variable extends string = CssVariable> =
  | CssVars<Variable>
  | 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: AngleSliderProps;
  ref: HTMLDivElement;
  stylesNames: AngleSliderStylesNames;
  vars: AngleSliderCssVariables;
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<AngleSliderFactory>
React.ElementType
Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>
React.ComponentProps<ElementType>
ElementType
PropsToOmit
React.ReactNode
React.ComponentProps<'input'>
HTMLDivElement
```
