Understanding Material UI Flex Direction

Flexbox is a popular layout system in CSS that is widely used by web developers to create complex designs with ease. Material UI, a popular React UI framework also uses flexbox for layout purposes. In Material UI, the Flexbox layout is achieved through the use of the display: flex property. This property is used to create a flexible container to hold the elements inside.

What is Flex Direction in Material UI?

The flex-direction property is used to determine the direction in which the elements should be laid out in the flexible container. The default value of this property is row, which means that the elements are laid out horizontally. However, this property can take four possible values which are:

  • row: This is the default value and it lays out the elements in a horizontal direction, from left to right.
  • row-reverse: This lays out the elements in a horizontal direction, from right to left.
  • column: This lays out the elements in a vertical direction, from top to bottom.
  • column-reverse: This lays out the elements in a vertical direction, from bottom to top.

How to use Flex Direction in Material UI?

To use flex direction in Material UI, you simply need to add it as a value for the flexDirection attribute in the style object of the container element. Here's an example:

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import { Box } from '@material-ui/core';

const useStyles = makeStyles({
  container: {
    display: 'flex',
    flexDirection: 'row',

function MyComponent() {
  const classes = useStyles();
  return (
      Element 1
      Element 2
      Element 3

export default MyComponent;

In this example, we are creating a Box component with a class name of container. We add the display: flex property to make it a flex container and also add the flexDirection: row property to lay out the elements in a horizontal direction.

You can also use this property with other Material UI layout components like Grid,Card,Table, etc. to create complex layouts easily.


Flexbox is a powerful tool in CSS that simplifies the layout process for web developers. The flex-direction property is an important aspect of the flexbox layout system that determines the direction of the elements in the container. In Material UI, you can use this property easily to create flexible and responsive layouts.
