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

Toggle a navigation menu visually.

## 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 |
| --- | --- |
| `Burger.opened` | Whether the controlled region is open. |
| `Burger.onClick` | Local click handler; replace demo logic with an explicit business action. |
| `Burger.aria-label` | Accessible name/state for the native element. |

## 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 [open, setOpen] = useState(false);
return <M.Burger opened={open} onClick={() => setOpen(!open)} aria-label="Toggle navigation" />;
}
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

The `Burger` component renders an open/close menu button.
Set the `opened` and `onClick` props to control the component state.
If the `opened` prop is set, a cross will be rendered, otherwise a burger icon.



## Change line size




## Accessibility

To make the `Burger` accessible for screen readers, you need to either set `aria-label` or
use the [VisuallyHidden](/core/visually-hidden) component:

```tsx
import { Burger, VisuallyHidden } from '@mantine/core';

function Demo() {
  return (
    <>
      <Burger aria-label="Toggle navigation" />

      <Burger>
        <VisuallyHidden>Toggle navigation</VisuallyHidden>
      </Burger>
    </>
  );
}
```


## 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
Burger(_props)
```



```ts
export type BurgerStylesNames = 'root' | 'burger';

export type BurgerCssVariables = {
  root:
    | '--burger-color'
    | '--burger-size'
    | '--burger-line-size'
    | '--burger-transition-duration'
    | '--burger-transition-timing-function';
};

export interface BurgerProps
  extends BoxProps, StylesApiProps<BurgerFactory>, ElementProps<'button'> {
  /** Controls burger `width` and `height`, numbers are converted to rem @default 'md' */
  size?: MantineSize | (string & {}) | number;

  /** Controls height of lines, by default calculated based on `size` prop */
  lineSize?: string | number;

  /** Key of `theme.colors` of any valid CSS value, by default `theme.white` in dark color scheme and `theme.black` in light */
  color?: MantineColor;

  /** State of the burger, when `true` burger is transformed into X @default false */
  opened?: boolean;

  /** `transition-duration` property value in ms @default 300 */
  transitionDuration?: number;

  /** `transition-timing-function` property value @default 'ease' */
  transitionTimingFunction?: string;
}

export type BurgerFactory = Factory<{
  props: BurgerProps;
  ref: HTMLButtonElement;
  stylesNames: BurgerStylesNames;
  vars: BurgerCssVariables;
}>;

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: BurgerProps;
  ref: HTMLButtonElement;
  stylesNames: BurgerStylesNames;
  vars: BurgerCssVariables;
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<BurgerFactory>
React.ElementType
Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>
React.ComponentProps<ElementType>
ElementType
PropsToOmit
MantineSize
MantineColor
HTMLButtonElement
```
