I am currently building a dashboard layout using the MUI-5 drawer component. My aim is to position the open-close button of the drawer at the center-right corner. However, I am facing some issues with the implementation. Although I can place the icon at the center using absolute positioning, half the button gets hidden. Below is the current code implementation of the dashboard layout using MUI-5 drawer component:

import { PropsWithChildren, useState } from 'react';
import { styled, useTheme, Theme, CSSObject } from '@mui/material/styles';
import Box from '@mui/material/Box';
import MuiDrawer from '@mui/material/Drawer';
import MuiAppBar, { AppBarProps as MuiAppBarProps } from '@mui/material/AppBar';
import Toolbar from '@mui/material/Toolbar';
import List from '@mui/material/List';
import CssBaseline from '@mui/material/CssBaseline';
import Typography from '@mui/material/Typography';
import Divider from '@mui/material/Divider';
import IconButton from '@mui/material/IconButton';
import MenuIcon from '@mui/icons-material/Menu';
import ChevronLeftIcon from '@mui/icons-material/ChevronLeft';
import ChevronRightIcon from '@mui/icons-material/ChevronRight';
import ListItem from '@mui/material/ListItem';
import ListItemButton from '@mui/material/ListItemButton';
import ListItemIcon from '@mui/material/ListItemIcon';
import ListItemText from '@mui/material/ListItemText';
import InboxIcon from '@mui/icons-material/MoveToInbox';
import MailIcon from '@mui/icons-material/Mail';
import { Grid, SvgIcon } from '@mui/material';

import Test from '../assets/Subtract.svg';

import Logo from '../assets/logo-dash.png';

const drawerWidth = 240;

const openedMixin = (theme: Theme): CSSObject => ({
  width: drawerWidth,
  transition: theme.transitions.create('width', {
    easing: theme.transitions.easing.sharp,
    duration: theme.transitions.duration.enteringScreen,
  }),
  overflowX: 'hidden',
});

const closedMixin = (theme: Theme): CSSObject => ({
  transition: theme.transitions.create('width', {
    easing: theme.transitions.easing.sharp,
    duration: theme.transitions.duration.leavingScreen,
  }),
  overflowX: 'hidden',
  width: `calc(${theme.spacing(7)} + 1px)`,
  [theme.breakpoints.up('sm')]: {
    width: `calc(${theme.spacing(8)} + 1px)`,
  },
});

const DrawerHeader = styled('div')(({ theme }) => ({
  display: 'flex',
  alignItems: 'center',
  justifyContent: 'flex-end',
  padding: theme.spacing(0, 1),
  // necessary for content to be below app bar
  ...theme.mixins.toolbar,
}));

interface AppBarProps extends MuiAppBarProps {
  open?: boolean;
}

const ExpandableDrawer = styled(Grid, {
  shouldForwardProp: (prop) => prop !== 'open',
})<AppBarProps>(({ theme, open }) => ({
  zIndex: theme.zIndex.drawer + 1,
  transition: theme.transitions.create(['width', 'margin'], {
    easing: theme.transitions.easing.sharp,
    duration: theme.transitions.duration.leavingScreen,
  }),
  ...(open && {
    marginLeft: drawerWidth,
    width: `calc(100% - ${drawerWidth}px)`,
    transition: theme.transitions.create(['width', 'margin'], {
      easing: theme.transitions.easing.sharp,
      duration: theme.transitions.duration.enteringScreen,
    }),
  }),
}));

const Drawer = styled(MuiDrawer, {
  shouldForwardProp: (prop) => prop !== 'open',
})(({ theme, open }) => ({
  width: drawerWidth,
  flexShrink: 0,
  whiteSpace: 'nowrap',
  boxSizing: 'border-box',
  ...(open && {
    ...openedMixin(theme),
    '& .MuiDrawer-paper': openedMixin(theme),
  }),
  ...(!open && {
    ...closedMixin(theme),
    '& .MuiDrawer-paper': closedMixin(theme),
  }),
}));

export default function DashboardDrawer({ children }: PropsWithChildren) {
  const theme = useTheme();
  const [open, setOpen] = useState(false);

  const handleDrawerOpen = () => {
    setOpen(true);
  };

  const handleDrawerClose = () => {
    setOpen(false);
  };

Here is an expected UI image that shows the desired position of the icon: To achieve the desired position, I have made changes to the code for the button's absolute positioning. By adding the `position: 'absolute'` and `right: '5px'` properties to the button style class, the button gets correctly positioned. You can check the modified code snippet below:

I hope this solves your issue. Let me know if you have any further questions.
