# App Bar

The App Bar displays information and actions relating to the current screen.

The top App bar provides content and actions related to the current screen. It's used for branding, screen titles, navigation, and actions.

It can transform into a contextual action bar or be used as a navbar.

import Toolbar from '@mui/material/Toolbar';
import Typography from '@mui/material/Typography';
import Button from '@mui/material/Button';
import IconButton from '@mui/material/IconButton';
import MenuIcon from '@mui/icons-material/Menu';

export default function ButtonAppBar() {
  return (
    <Box sx={{ flexGrow: 1 }}>
      <AppBar position="static">
        <Toolbar>
          <IconButton
            size="large"
            edge="start"
            color="inherit"
            aria-label="menu"
            sx={{ mr: 2 }}
          >

          </IconButton>
        </Toolbar>
      </AppBar>
    </React.Fragment>
  );
}

```

## Fixed placement

When you render the app bar position fixed, the dimension of the element doesn't impact the rest of the page. This can cause some part of your content to be invisible, behind the app bar. Here are 3 possible solutions:

1. You can use `position="sticky"` instead of fixed.
2. You can render a second `<Toolbar />` component:

```jsx
function App() {
  return (
    <React.Fragment>
      <AppBar position="fixed">
        <Toolbar>{/* content */}</Toolbar>
      </AppBar>
      <Toolbar />
    </React.Fragment>
  );
}
```

3. You can use `theme.mixins.toolbar` CSS:

```jsx
const Offset = styled('div')(({ theme }) => theme.mixins.toolbar);

function App() {
  return (
    <React.Fragment>
      <AppBar position="fixed">
        <Toolbar>{/* content */}</Toolbar>
      </AppBar>
      <Offset />
    </React.Fragment>
  );
}
```

## Scrolling

You can use the `useScrollTrigger()` hook to respond to user scroll actions.

### Hide App bar

The app bar hides on scroll down to leave more space for reading.

```tsx
import * as React from 'react';
import AppBar from '@mui/material/AppBar';
import Toolbar from '@mui/material/Toolbar';
import Typography from '@mui/material/Typography';
import CssBaseline from '@mui/material/CssBaseline';
import useScrollTrigger from '@mui/material/useScrollTrigger';
import Box from '@mui/material/Box';
import Container from '@mui/material/Container';
import Slide from '@mui/material/Slide';

interface Props {
  /**
   * Injected by the documentation to work in an iframe.
   * You won't need it on your project.
   */
  window?: () => Window;
  children?: React.ReactElement<unknown>;
}

function HideOnScroll(props: Props) {
  const { children, window } = props;
  // Note that you normally won't need to set the window ref as useScrollTrigger
  // will default to window.
  // This is only being set here because the demo is in an iframe.
  const trigger = useScrollTrigger({
    target: window ? window() : undefined,
  });

  return (
    <Slide appear={false} direction="down" in={!trigger}>
      {children ?? <div />}
    </Slide>
  );
}

export default function HideAppBar(props: Props) {
  return (
    <React.Fragment>
      <CssBaseline />
      <HideOnScroll {...props}>
        <AppBar>
          <Toolbar>
            <Typography variant="h6" component="div">
              Scroll to hide App bar
            </Typography>
          </Toolbar>
        </AppBar>
      </HideOnScroll>
      <Toolbar />
      <Container>
        <Box sx={{ my: 2 }}>
          {[...new Array(12)]
            .map(
              () => `Cras mattis consectetur purus sit amet fermentum.
Cras justo odio, dapibus ac facilisis in, egestas eget quam.
Morbi leo risus, porta ac consectetur ac, vestibulum at eros.
Praesent commodo cursus magna, vel scelerisque nisl consectetur et.`,
            )
            .join('\n')}
        </Box>
      </Container>
    </React.Fragment>
  );
}

```

### Elevate App bar

The app bar elevates on scroll to communicate that the user is not at the top of the page.

```tsx
import * as React from 'react';
import AppBar from '@mui/material/AppBar';
import Toolbar from '@mui/material/Toolbar';
import Typography from '@mui/material/Typography';
import CssBaseline from '@mui/material/CssBaseline';
import useScrollTrigger from '@mui/material/useScrollTrigger';
import Box from '@mui/material/Box';
import Container from '@mui/material/Container';

interface Props {
  /**
   * Injected by the documentation to work in an iframe.
   * You won't need it on your project.
   */
  window?: () => Window;
  children?: React.ReactElement<{ elevation?: number }>;
}

function ElevationScroll(props: Props) {
  const { children, window } = props;
  // Note that you normally won't need to set the window ref as useScrollTrigger
  // will default to window.
  // This is only being set here because the demo is in an iframe.
  const trigger = useScrollTrigger({
    disableHysteresis: true,
    threshold: 0,
    target: window ? window() : undefined,
  });

  return children
    ? React.cloneElement(children, {
        elevation: trigger ? 4 : 0,
      })
    : null;
}

export default function ElevateAppBar(props: Props) {
  return (
    <React.Fragment>
      <CssBaseline />
      <ElevationScroll {...props}>
        <AppBar>
          <Toolbar>
            <Typography variant="h6" component="div">
              Scroll to elevate App bar
            </Typography>
          </Toolbar>
        </AppBar>
      </ElevationScroll>
      <Toolbar />
      <Container>
        <Box sx={{ my: 2 }}>
          {[...new Array(12)]
            .map(
              () => `Cras mattis consectetur purus sit amet fermentum.
Cras justo odio, dapibus ac facilisis in, egestas eget quam.
Morbi leo risus, porta ac consectetur ac, vestibulum at eros.
Praesent commodo cursus magna, vel scelerisque nisl consectetur et.`,
            )
            .join('\n')}
        </Box>
      </Container>
    </React.Fragment>

### Back to top

A floating action button appears on scroll to make it easy to get back to the top of the page.

```tsx
import * as React from 'react';
import AppBar from '@mui/material/AppBar';
import Toolbar from '@mui/material/Toolbar';
import Typography from '@mui/material/Typography';
import CssBaseline from '@mui/material/CssBaseline';
import useScrollTrigger from '@mui/material/useScrollTrigger';
import Box from '@mui/material/Box';
import Container from '@mui/material/Container';
import Fab from '@mui/material/Fab';
import KeyboardArrowUpIcon from '@mui/icons-material/KeyboardArrowUp';
import Fade from '@mui/material/Fade';

interface Props {
  /**
   * Injected by the documentation to work in an iframe.
   * You won't need it on your project.
   */
  window?: () => Window;
  children?: React.ReactElement<unknown>;
}

function ScrollTop(props: Props) {
  const { children, window } = props;
  // Note that you normally won't need to set the window ref as useScrollTrigger
  // will default to window.
  // This is only being set here because the demo is in an iframe.
  const trigger = useScrollTrigger({
    target: window ? window() : undefined,
    disableHysteresis: true,
    threshold: 100,
  });

  const handleClick = (event: React.MouseEvent<HTMLDivElement>) => {
    const anchor = (
      (event.target as HTMLDivElement).ownerDocument || document
    ).querySelector('#back-to-top-anchor');

    if (anchor) {
      anchor.scrollIntoView({
        block: 'center',
      });
    }
  };

  return (
    <Fade in={trigger}>
      <Box
        onClick={handleClick}
        role="presentation"
        sx={{ position: 'fixed', bottom: 16, right: 16 }}
      >
        {children}
      </Box>
    </Fade>
  );
}

export default function BackToTop(props: Props) {
  return (
    <React.Fragment>
      <CssBaseline />
      <AppBar>
        <Toolbar>
          <Typography variant="h6" component="div">
            Scroll to see button
          </Typography>
        </Toolbar>
      </AppBar>
      <Toolbar id="back-to-top-anchor" />
      <Container>
        <Box sx={{ my: 2 }}>
          {[...new Array(12)]
            .map(
              () => `Cras mattis consectetur purus sit amet fermentum.
Cras justo odio, dapibus ac facilisis in, egestas eget quam.
Morbi leo risus, porta ac consectetur ac, vestibulum at eros.
Praesent commodo cursus magna, vel scelerisque nisl consectetur et.`,
            )
            .join('\n')}
        </Box>
      </Container>
      <ScrollTop {...props}>
        <Fab size="small" aria-label="scroll back to top">
          <KeyboardArrowUpIcon />
        </Fab>
      </ScrollTop>
    </React.Fragment>
  );
}

```

### `useScrollTrigger([options]) => trigger`

#### Arguments

1. `options` (_object_ [optional]):
   - `options.disableHysteresis` (_bool_ [optional]): Defaults to `false`. Disable the hysteresis. Ignore the scroll direction when determining the `trigger` value.
   - `options.target` (_Node_ [optional]): Defaults to `window`.
   - `options.threshold` (_number_ [optional]): Defaults to `100`. Change the `trigger` value when the vertical scroll strictly crosses this threshold (exclusive).

#### Returns

`trigger`: Does the scroll position match the criteria?

#### Examples

```jsx
import useScrollTrigger from '@mui/material/useScrollTrigger';

function HideOnScroll(props) {
  const trigger = useScrollTrigger();
  return (
    <Slide in={!trigger}>
      <div>Hello</div>
    </Slide>
  );
}
```

## Enable color on dark

Following the [Material Design guidelines](https://m2.material.io/design/color/dark-theme.html), the `color` prop has no effect on the appearance of the app bar in dark mode.
You can override this behavior by setting the `enableColorOnDark` prop to `true`.

```tsx
import AppBar from '@mui/material/AppBar';
import Stack from '@mui/material/Stack';
import Toolbar from '@mui/material/Toolbar';
import Typography from '@mui/material/Typography';
import IconButton from '@mui/material/IconButton';
import MenuIcon from '@mui/icons-material/Menu';
import { ThemeProvider, createTheme } from '@mui/material/styles';

function appBarLabel(label: string) {
  return (
    <Toolbar>
      <IconButton edge="start" color="inherit" aria-label="menu" sx={{ mr: 2 }}>
        <MenuIcon />
      </IconButton>
      <Typography variant="h6" noWrap component="div" sx={{ flexGrow: 1 }}>
        {label}
      </Typography>
    </Toolbar>
  );
}

const darkTheme = createTheme({
  palette: {
    mode: 'dark',
    primary: {
      main: '#1976d2',
    },
  },
});

export default function EnableColorOnDarkAppBar() {
  return (
    <Stack spacing={2} sx={{ flexGrow: 1 }}>
      <ThemeProvider theme={darkTheme}>
        <AppBar position="static" color="primary" enableColorOnDark>
          {appBarLabel('enableColorOnDark')}
        </AppBar>
        <AppBar position="static" color="primary">
          {appBarLabel('default')}
        </AppBar>
      </ThemeProvider>
    </Stack>
  );
}

```
