Stack

The Stack component is the basic layout component, used to build horizontal and vertical flows, grids, dashboards, etc...

For information about views layouts in general as well as common layout patterns, see Layout.

Columns (vertical)

By default, a stack renders components in a vertical flow with spacing in between.

To force a stack to scroll, add a max height and scroll bars will automatically appear.

Rows (horizontal)

A stack can render components in a horizontal flow by setting direction="row"

If the components in a row stack grow too large to fit in a row, they will wrap around onto the next row.

Spacing

Use the spacing prop to configure the amount of space between each item of the stack.

Grow

By default, components in a stack will fit their content. To force components to grow to fill all horizontal or vertical space set the grow prop.

Justify

Justify defines the alignment across the main axis (the horizontal axis for a horizontal stack and the vertical axis for a vertical stack).

Align

Align defines the alignment across the cross axis (the vertical axis for a horizontal stack and the horizontal axis for a vertical stack).

Configuring stack children

You can customize the width and offset of a component that is a direct child of a stack.

width and offset only work on Airplane components that are direct children of a <Stack>. If you want to set these props on custom components, see Setting the width and offset of a custom component.

Width

If you need more control over a component's width, set the width prop on a component that is a direct child of a <Stack>. width can take a few values:

content (default): The component fits its content.
auto: The component grows to fit available space. All components in a given row with with auto will be the same size as long as there is enough room to fit their content.
numerical size: The share of the row that the component takes up as a percentage (e.g. "50%"), a fraction (e.g. "1/2") or a number in a 12 column grid (e.g. 6).

Offset

You can offset a component that is a direct child of a <Stack> using the same units as width (percentage, fraction, or number of 12 column grid). The offset is added to the left of the component.

Responsive widths

To customize layouts for different size screens, you can set breakpoints in a component's width or offset. Both the width and offset props can take an object that specifies the value for a particular screen size and above.

Available breakpoints include:

xs: 0px and up
sm: 768px and up
md: 992px and up
lg: 1200px and up
xl: 1400px and up

A breakpoint matches if the screen size is greater than or equal to the breakpoint. The largest breakpoint that matches is applied.

For example, A 1000px screen matches xs, sm and md. If you set the width of a component to {xs: 100%, md: 50%}, the md value will be chosen since it is the largest breakpoint that matches.

In the following example, each component has a 33% width if the screen is size sm or larger, and 100% if the screen is size xs. Try decreasing the size of your window and watch the components expand to fill 100% of the row.

Remember that if the components in a row stack grow too large to fit in a row, they will automatically wrap around onto the next row. Breakpoints are not always necessary because this wrapping behavior ensures that content fits even if breakpoints are not set.

Setting the width and offset of a custom component

If you want to set the width or offset of a custom component that is a direct child of a <Stack>, you can wrap the component in a <Stack.Item>.

This works for built in React components (like <div>), third party components, or your own custom components.

Component API

Name	Description	Default
children	Component Items of the stack. To specify custom spacing, breakpoints, or offset, use <Stack.Item>.
direction	"row" \| "column" Direction of the stack.	column
justify	"start" \| "end" \| "center" \| "space-between" \| "space-around" Position of the stack on the vertical axis for column stacks and the horizontal axis for row stacks.	start
align	"start" \| "end" \| "center" \| "stretch" Alignment of the stack on the horizontal axis for column stacks and the vertical axis for row stacks.	stretch
spacing	number \| "xs" \| "sm" \| "md" \| "lg" \| "xl" Spacing between items of the stack.	md
grow	boolean Grow the items of the stack to fill the available space.	false
sx	CSSObject CSS style overrides.
className	string A string representing the class of the element.
width	number \| "content" \| "auto" \| `${number}%` \| `${number}/${number}` \| { xs?: ColWidth; sm?: ColWidth; md?: ColWidth; lg?: ColWidth; xl?: ColWidth; } Width of the component. This component must be a direct child of a <Stack> for this prop to take effect. If an integer is specified, signifies the width in a 12 item grid. 12 means that the component takes up the entire row, 6 is half, 1 is 1/12. If a decimal or fraction is specified, signifies the fractional share of the row. e.g. 1/2 takes up half of the row. If a percentage is specified, signifies the percentage share of the row. e.g. "50%" takes up half of the row. content indicates that the component should take up as much space as its content. auto indicates that the component should take any leftover space on the row. To set width based on the screen size, use an object with a specific width for each breakpoint. e.g. {xs: "100%", md: "50%"} sets the width on xs-md screens to 100% and md and larger screens to 50%.	content
offset	number \| `${number}%` \| `${number}/${number}` \| { xs?: ColOffset; sm?: ColOffset; md?: ColOffset; lg?: ColOffset; xl?: ColOffset; } Creates a gap to the left of the component. Has the same units as width. This component must be a direct child of a <Stack> for this prop to take effect. If an integer is specified, signifies the offset in a 12 item grid. 6 means the component is offset by half a row, 1 is 1/12 of a row. If a decimal or fraction is specified, signifies the fractional share of the row. e.g. 1/2 offsets a component by half of the row. If a percentage is specified, signifies the percentage share of the row. e.g. "50%" offsets a component by half of the row. To set offset based on the screen size, use an object with a specific offset for each breakpoint. e.g. {xs: "50%", md: "0%"} sets the offset on xs-md screens to 50% and md and larger screens to 0%.
