Divider
A divider is a thin line that groups content in lists and layouts.
Dividers separate content into clear groups.
List Dividers
The divider renders as an <hr> by default.
You can save rendering this DOM element by using the divider property on the ListItem component.
<List component="nav" className={classes.root} aria-label="mailbox folders">
  <ListItem button>
    <ListItemText primary="Inbox" />
  </ListItem>
  <Divider />
  <ListItem button divider>
    <ListItemText primary="Drafts" />
  </ListItem>
  <ListItem button>
    <ListItemText primary="Trash" />
  </ListItem>
  <Divider light />
  <ListItem button>
    <ListItemText primary="Spam" />
  </ListItem>
</List>HTML5 Specification
In a list, you should ensure the Divider is rendered as an <li> to match the HTML5 specification.
The examples below show two ways of achieving this.

Vertical Dividers
You can also render a divider vertically using the orientation prop.
Note the use of the flexItem prop to accommodate for the flex container.
<Grid container alignItems="center" className={classes.root}>
  <FormatAlignLeftIcon />
  <FormatAlignCenterIcon />
  <FormatAlignRightIcon />
  <Divider orientation="vertical" flexItem />
  <FormatBoldIcon />
  <FormatItalicIcon />
  <FormatUnderlinedIcon />
</Grid>
