Divider

The Divider component provides a thin, unobtrusive line for grouping elements to reinforce visual hierarchy.

Introduction

The Material UI Divider component renders as a dark gray <hr> by default, and features several useful props for quick style adjustments.

import * as React from 'react';
import Card from '@mui/material/Card';
import Box from '@mui/material/Box';
import Chip from '@mui/material/Chip';
import Stack from '@mui/material/Stack';
import Divider from '@mui/material/Divider';
import Typography from '@mui/material/Typography';

export default function IntroDivider() {
  return (
    <Card variant="outlined" sx={{ maxWidth: 360 }}>
      <Box sx={{ p: 2 }}>
        <Stack
          direction="row"
          sx={{ justifyContent: 'space-between', alignItems: 'center' }}
        >
          <Typography gutterBottom variant="h5" component="div">
            Toothbrush
          </Typography>
          <Typography gutterBottom variant="h6" component="div">
            $4.50
          </Typography>
        </Stack>
        <Typography variant="body2" sx={{ color: 'text.secondary' }}>
          Pinstriped cornflower blue cotton blouse takes you on a walk to the park or
          just down the hall.
        </Typography>
      </Box>
      <Divider />
      <Box sx={{ p: 2 }}>
        <Typography gutterBottom variant="body2">
          Select type
        </Typography>
        <Stack direction="row" spacing={1}>
          <Chip color="primary" label="Soft" size="small" />
          <Chip label="Medium" size="small" />
          <Chip label="Hard" size="small" />
        </Stack>
      </Box>
    </Card>
  );
}

Basics

import Divider from '@mui/material/Divider';

Variants

The Divider component supports three variants: fullWidth (default), inset, and middle.

import * as React from 'react';
import List from '@mui/material/List';
import ListItem from '@mui/material/ListItem';
import ListItemText from '@mui/material/ListItemText';
import Divider from '@mui/material/Divider';

const style = {
  py: 0,
  width: '100%',
  maxWidth: 360,
  borderRadius: 2,
  border: '1px solid',
  borderColor: 'divider',
  backgroundColor: 'background.paper',
};

export default function DividerVariants() {
  return (
    <List sx={style}>
      <ListItem>
        <ListItemText primary="Full width variant below" />
      </ListItem>
      <Divider component="li" />
      <ListItem>
        <ListItemText primary="Inset variant below" />
      </ListItem>
      <Divider variant="inset" component="li" />
      <ListItem>
        <ListItemText primary="Middle variant below" />
      </ListItem>
      <Divider variant="middle" component="li" />
      <ListItem>
        <ListItemText primary="List item" />
      </ListItem>
    </List>
  );
}

Orientation

Use the orientation prop to change the Divider from horizontal to vertical. When using vertical orientation, the Divider renders a <div> with the corresponding accessibility attributes instead of <hr> to adhere to the WAI-ARIA spec.

import * as React from 'react';
import FormatAlignLeftIcon from '@mui/icons-material/FormatAlignLeft';
import FormatAlignCenterIcon from '@mui/icons-material/FormatAlignCenter';
import FormatAlignRightIcon from '@mui/icons-material/FormatAlignRight';
import FormatBoldIcon from '@mui/icons-material/FormatBold';
import Box from '@mui/material/Box';
import Divider, { dividerClasses } from '@mui/material/Divider';

export default function VerticalDividers() {
  return (
    <Box
      sx={{
        display: 'flex',
        alignItems: 'center',
        border: '1px solid',
        borderColor: 'divider',
        borderRadius: 1,
        bgcolor: 'background.paper',
        color: 'text.secondary',
        '& svg': {
          m: 1,
        },
        [`& .${dividerClasses.root}`]: {
          mx: 0.5,
        },
      }}
    >
      <FormatAlignLeftIcon />
      <FormatAlignCenterIcon />
      <FormatAlignRightIcon />
      <Divider orientation="vertical" flexItem />
      <FormatBoldIcon />
    </Box>
  );
}

Flex item

Use the flexItem prop to display the Divider when it’s being used in a flex container.

import * as React from 'react';
import FormatBoldIcon from '@mui/icons-material/FormatBold';
import FormatItalicIcon from '@mui/icons-material/FormatItalic';
import Box from '@mui/material/Box';
import Divider from '@mui/material/Divider';

export default function FlexDivider() {
  return (
    <Box
      sx={{
        display: 'inline-flex',
        alignItems: 'center',
        border: '1px solid',
        borderColor: 'divider',
        borderRadius: 2,
        bgcolor: 'background.paper',
        color: 'text.secondary',
        '& svg': {
          m: 1,
        },
      }}
    >
      <FormatBoldIcon />
      <Divider orientation="vertical" variant="middle" flexItem />
      <FormatItalicIcon />
    </Box>
  );
}

With children

Use the textAlign prop to align elements that are wrapped by the Divider.

import * as React from 'react';
import { styled } from '@mui/material/styles';
import Divider from '@mui/material/Divider';
import Chip from '@mui/material/Chip';

const Root = styled('div')(({ theme }) => ({
  width: '100%',
  ...theme.typography.body2,
  color: theme.palette.text.secondary,
  '& > :not(style) ~ :not(style)': {
    marginTop: theme.spacing(2),
  },
}));

export default function DividerText() {
  const content = (
    <p>{`Lorem ipsum dolor sit amet, consectetur adipiscing elit.`}</p>
  );

  return (
    <Root>
      {content}
      <Divider>CENTER</Divider>
      {content}
      <Divider textAlign="left">LEFT</Divider>
      {content}
      <Divider textAlign="right">RIGHT</Divider>
      {content}
      <Divider>
        <Chip label="Chip" size="small" />
      </Divider>
      {content}
    </Root>
  );
}

Customization

Use with a List

When using the Divider to separate items in a List, use the component prop to render it as an <li>—otherwise it won’t be a valid HTML element.

import * as React from 'react';
import List from '@mui/material/List';
import ListItem from '@mui/material/ListItem';
import ListItemText from '@mui/material/ListItemText';
import Divider from '@mui/material/Divider';

const style = {
  p: 0,
  width: '100%',
  maxWidth: 360,
  borderRadius: 2,
  border: '1px solid',
  borderColor: 'divider',
  backgroundColor: 'background.paper',
};

export default function ListDividers() {
  return (
    <List sx={style} aria-label="mailbox folders">
      <ListItem>
        <ListItemText primary="Inbox" />
      </ListItem>
      <Divider component="li" />
      <ListItem>
        <ListItemText primary="Drafts" />
      </ListItem>
      <Divider component="li" />
      <ListItem>
        <ListItemText primary="Trash" />
      </ListItem>
      <Divider component="li" />
      <ListItem>
        <ListItemText primary="Spam" />
      </ListItem>
    </List>
  );
}

Icon grouping

The demo below shows how to combine the props variant="middle" and orientation="vertical".

import * as React from 'react';
import Card from '@mui/material/Card';
import Divider, { dividerClasses } from '@mui/material/Divider';
import FormatAlignLeftIcon from '@mui/icons-material/FormatAlignLeft';
import FormatAlignCenterIcon from '@mui/icons-material/FormatAlignCenter';
import FormatAlignRightIcon from '@mui/icons-material/FormatAlignRight';
import FormatBoldIcon from '@mui/icons-material/FormatBold';

export default function VerticalDividerMiddle() {
  return (
    <Card
      variant="outlined"
      sx={{
        display: 'flex',
        color: 'text.secondary',
        '& svg': {
          m: 1,
        },
        [`& .${dividerClasses.root}`]: {
          mx: 0.5,
        },
      }}
    >
      <FormatAlignLeftIcon />
      <FormatAlignCenterIcon />
      <FormatAlignRightIcon />
      <Divider orientation="vertical" variant="middle" flexItem />
      <FormatBoldIcon />
    </Card>
  );
}

Accessibility

Due to its implicit role of separator, the Divider, which is a <hr> element, will be announced by screen readers as a “Horziontal Splitter” (or vertical, if you’re using the orientation prop).

If you’re using it as a purely stylistic element, we recommend setting aria-hidden="true" which will make screen readers bypass it.

<Divider aria-hidden="true" />

If you’re using the Divider to wrap other elements, such as text or chips, we recommend changing its rendered element to a plain <div> using the component prop, and setting role="presentation". This ensures that it’s not announced by screen readers while still preserving the semantics of the elements inside it.

<Divider component="div" role="presentation">
  <Typography>Text element</Typography>
</Divider>

Anatomy

The Divider component is composed of a root <hr>.

<hr class="MuiDivider-root">
  <!-- Divider children goes here -->
</hr>
