            </List>
            <ListItem className={clsx(classes.firebase, classes.item, classes.itemCategory, classes.drawerFooter)}>
                Footer
            </ListItem>
        </div>
    )

    return (
        <Wrapper>
            <Drawer
                className={classes.root}
                variant="permanent"
                anchor="right"
            >{drawer}</Drawer>
        </Wrapper>
    );
}

export default Sidebar;

and this is the image of that:

How should I stick the footer section to the bottom of the drawer? I set the bottom to zero for the ListItem of the footer in its CSS code but doesn't work properly!:( and when I change the position of footer item into fixed, the width of the footer is not fit to the drawer. like this image:

Answers

There is a simple solution to this. Instead of using a list item to create the footer just use a simple div & give it a class that makes it go to the bottom of your drawer.

Your current code:

<ListItem className={clsx(classes.firebase, classes.item, classes.itemCategory, classes.drawerFooter)}>
    Footer
</ListItem>

Instead use:

<div className={classes.bottomPush}>
    <Typography>Footer</Typography>
</div>

For the class use:

bottomPush: {
    position: "fixed",
    bottom: 0,
    textAlign: "center",
    paddingBottom: 10,
}
