Component demos

For examples and details on the usage of this React component, visit the component demo pages:

import Stack from '@mui/system/Stack';
// or
import { Stack } from '@mui/system';

Props of the native component are also available.

Name	Type	Description
children	node	The content of the component.
component	elementType	The component used for the root node. Either a string to use a HTML element or a component.
direction	'column-reverse' \| 'column' \| 'row-reverse' \| 'row' \| Array<'column-reverse' \| 'column' \| 'row-reverse' \| 'row'> \| object	Defines the `flex-direction` style property. It is applied for all screen sizes.
divider	node	Add an element between each child.
spacing	Array<number \| string> \| number \| object \| string	Defines the space between immediate children.
sx	Array<func \| object \| bool> \| func \| object	The system prop, which allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
useFlexGap	bool	If `true`, the CSS flexbox `gap` is used instead of applying `margin` to children. While CSS `gap` removes the known limitations, it is not fully supported in some browsers. We recommend checking https://caniuse.com/?search=flex%20gap before using this flag. To enable this flag globally, follow the theme's default props configuration.

As a CSS utility, the Stack component also supports all system properties. You can use them as props directly on the component.

The ref is forwarded to the root element.

You can use MuiStack to change the default props of this component with the theme.

These class names are useful for styling with CSS. They are applied to the component's slots when specific states are triggered.

Class name	Rule name	Description
.MuiStack-root	root	Styles applied to the root element.

You can override the style of the component using one of these customization options:

With a global class name.
With a rule name as part of the component's styleOverrides property in a custom theme.
