How to access the removed header area in this drawer template in Material UI (MUI)?-CodePudding

I'm currently exploring MUI, thus I used a drawer template from MUI and wanted to customize it a bit. I removed the header part of the template and may want to access the available space above by moving the text up until the available area but I'm having a difficulty on which I should tweak the code, especially in terms of grids or containers.

WITH HEADER (blue bar):

WITHOUT HEADER:

ACCESS THIS AREA:

Source code(jsx file):

import * as React from "react";
import Box from "@mui/material/Box";
import Drawer from "@mui/material/Drawer";
import CssBaseline from "@mui/material/CssBaseline";
import AppBar from "@mui/material/AppBar";

import List from "@mui/material/List";
import Typography from "@mui/material/Typography";

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";

const drawerWidth = 240;

export default function PermanentDrawerLeft() {
  return (
    <Box sx={{ display: "flex" }}>
      <CssBaseline />
      {/* <AppBar
        position="fixed"
        sx={{ width: `calc(100% - ${drawerWidth}px)`, ml: `${drawerWidth}px` }}

Your responses would help me a lot in terms of proper arrangement and accessing spaces. Thank you very much!

CodePudding user response：

In your code there is a <Toolbar/> component inside your <main> element. That is causing the blank area in top of your page. You can easily remove it.

And by the way there is another <Toolbar/> just like the previous one inside your <Drawer> component that caused the blank area in the top of the drawer (top left side of the page). You can delete that too.

Final code:

const drawerWidth = 240;

export default function Test() {
  return (
    <Box sx={{ display: "flex" }}>
      <CssBaseline />
      {/* <AppBar
        position="fixed"
        sx={{ width: `calc(100% - ${drawerWidth}px)`, ml: `${drawerWidth}px` }}
      >
        <Toolbar>
          <Typography variant="h6" noWrap component="div">
            Permanent drawer
          </Typography>
        </Toolbar>
      </AppBar>                  --- removed HEADER*/}    
      <Drawer
        sx={{
          width: drawerWidth,
          flexShrink: 0,

            width: drawerWidth,
            boxSizing: "border-box",
          },
        }}
        variant="permanent"
        anchor="left"

        {/* <Toolbar /> */}
        <Divider />
        <List>
