Material UI: drawer with expandable side menu

Question

Using Material UI, how can I construct a Drawer with expandable menu items like the one on the material-ui.com site?

So I want something like this:

Each menu item (in bold) can expand to reveal sub-menu items.

How can this be achieved with Material UI?

Answer 1

you need a function open and close collapse

const [openCollapse, setOpenCollapse] = React.useState(false);    
 
function handleOpenSettings(){
    setOpenCollapse(!openCollapse);
}

return(
        <Drawer>
            <ListItem button onClick={handleOpenSettings}>
              <ListItemIcon>
                <Settings />
              </ListItemIcon>
              <ListItemText primary="Settings" />
              {openCollapse ? <ExpandLess /> : <ExpandMore />}
            </ListItem>
            <Collapse in={openCollapse} timeout="auto" unmountOnExit>
            <List component="div" disablePadding>
              <ListItem button className={classes.nested}>
                <ListItemIcon>
                  <Settings />
                </ListItemIcon>
                <ListItemText inset primary="Starred" />
              </ListItem>
            </List>
          </Collapse>
        </Drawer>
)
