Migrate to Polaris

Version 2025-07 is the last API version to support React-based UI components. Later versions use web components, native UI elements with built-in accessibility, better performance, and consistent styling with Shopify's design system. Check out the migration guide to upgrade your extension.

GridItem

The GridItem component represents a single cell within a Grid layout, enabling you to control how content is positioned and sized within the grid. Use GridItem as a child of Grid to specify column span, row span, and positioning for individual content areas.

GridItem supports precise placement control through column and row properties, enabling you to create complex layouts where different items occupy varying amounts of space or appear in specific grid positions.

Support
Targets (25)

Configure the following properties on the GridItem component.

Anchor to accessibilityRole
accessibilityRole

The semantic meaning of the component's content. When set, assistive technologies use this role to help users navigate the page. Accepts a single role or a tuple of two roles (for example, ['listItem', 'separator']).

Anchor to background
background
<>
Default: 'transparent'

The background color of the element, set using a design-system keyword.

Anchor to border
border
<<>>

The border style of the element. Accepts a single value for all four edges, or a shorthand tuple for per-edge control:

  • 'base': Applies base to all edges.
  • ['base', 'none']: Block edges get base, inline edges get none.
  • ['base', 'none', 'dotted', 'base']: Values apply to block-start, inline-end, block-end, and inline-start respectively.
Anchor to borderWidth
borderWidth
< <> >

The border width of the element. Accepts a single value for all four edges, or a shorthand tuple for per-edge control:

  • 'base': Applies base to all edges.
  • ['base', 'medium']: Block edges get base, inline edges get medium.
  • ['base', 'medium', 'medium', 'base']: Values apply to block-start, inline-end, block-end, and inline-start respectively.
Anchor to columnSpan
columnSpan
<number>

The number of columns this item spans within the grid.

Anchor to cornerRadius
cornerRadius
< <> >

The corner radius of the element. Accepts a single value for all four corners, or a shorthand tuple for per-corner control using logical (writing-mode-aware) corners:

  • 'base': All four corners get base radius.
  • ['base', 'none']: StartStart/EndEnd get base, StartEnd/EndStart get none. In left-to-right mode, StartStart and EndEnd are the top-left and bottom-right corners.
  • ['base', 'none', 'small', 'base']: Values apply to StartStart, StartEnd, EndEnd, and EndStart respectively.

A borderRadius alias is available. When both are set, cornerRadius takes precedence.

Anchor to display
display
<'auto' | 'none'>
Default: 'auto'

The display mode of the component. Learn more about display.

  • auto: The initial value; the actual behavior depends on the component and context.
  • none: Hides the component and removes it from the accessibility tree.
string

A unique identifier for the component. Use this to target the component in scripts or stylesheets, or to distinguish it from other instances of the same component.

Anchor to maxBlockSize
maxBlockSize
< number | `${number}%` | 'fill' >

The maximum block size (maximum height in horizontal writing modes). The element won't grow taller than this value even if its content is longer.

  • number: The size in pixels.
  • `${number}%`: The size as a percentage of the parent container's block size.
  • 'fill': Takes all the available space.

Learn more about the max-block-size property.

Anchor to maxInlineSize
maxInlineSize
< number | `${number}%` | 'fill' >

The maximum inline size (maximum width in horizontal writing modes). The element won't grow wider than this value.

  • number: The size in pixels.
  • `${number}%`: The size as a percentage of the parent container's inline size.
  • 'fill': Takes all the available space.

Learn more about the max-inline-size property.

Anchor to minBlockSize
minBlockSize
< number | `${number}%` | 'fill' >

The minimum block size (minimum height in horizontal writing modes). The element won't shrink smaller than this value even if its content is shorter.

  • number: The size in pixels.
  • `${number}%`: The size as a percentage of the parent container's block size.
  • 'fill': Takes all the available space.

Learn more about the min-block-size property.

Anchor to minInlineSize
minInlineSize
< number | `${number}%` | 'fill' >

The minimum inline size (minimum width in horizontal writing modes). The element won't shrink narrower than this value.

  • number: The size in pixels.
  • `${number}%`: The size as a percentage of the parent container's inline size.
  • 'fill': Takes all the available space.

Learn more about the min-inline-size property.

Anchor to overflow
overflow
'hidden' | 'visible'
Default: 'visible'

The overflow behavior of the element.

  • visible: Content that extends beyond the container is visible.
  • hidden: Content that extends beyond the container is clipped and not scrollable.
Anchor to padding
padding
<<>>

The padding on all edges of the element, using a shorthand syntax. You can specify one, two, or four values following the CSS shorthand convention.

  • T: A single value applied uniformly to all edges.
  • [T, T]: The first value applies to block-start and block-end, the second to inline-start and inline-end.
  • [T, T, T, T]: Values apply to block-start, inline-end, block-end, and inline-start respectively.
Anchor to rowSpan
rowSpan
<number>

The number of rows this item spans within the grid.

Anchor to borderRadius
borderRadius
< <> >

The corner radius of the element. Accepts a single value for all four corners, or a shorthand tuple for per-corner control:

  • 'base': All four corners get base radius.
  • ['base', 'none']: StartStart/EndEnd get base, StartEnd/EndStart get none.
  • ['base', 'none', 'small', 'base']: Values apply to StartStart, StartEnd, EndEnd, and EndStart respectively.
Deprecated

Use cornerRadius instead.


Anchor to Span items across columnsSpan items across columns

Use GridItem with the columnSpan prop to make an element span multiple columns within a Grid layout. This example places a full-width header above two equal columns.

Span items across columns

A GridItem spanning multiple columns within a Grid.

Span items across columns

import {
reactExtension,
Grid,
GridItem,
View,
} from '@shopify/ui-extensions-react/customer-account';

export default reactExtension(
'customer-account.page.render',
() => <Extension />,
);

function Extension() {
return (
<Grid
columns={['20%', 'fill', 'auto']}
rows={[300, 'auto']}
spacing="loose"
>
<View border="base" padding="base">
20% / 300
</View>
<View border="base" padding="base">
fill / 300
</View>
<View border="base" padding="base">
auto / 300
</View>
<GridItem columnSpan={2}>
<View border="base" padding="base">
20% + fill / auto
</View>
</GridItem>
<View border="base" padding="base">
auto / auto
</View>
</Grid>
);
}
import {extension, Grid, GridItem, View} from '@shopify/ui-extensions/customer-account';

export default extension('customer-account.page.render', (root) => {
const grid = root.createComponent(
Grid,
{
columns: ['20%', 'fill', 'auto'],
rows: [300, 'auto'],
},
[
root.createComponent(
View,
{border: 'base', padding: 'base'},
'20% / 300',
),
root.createComponent(
View,
{border: 'base', padding: 'base'},
'fill / 300',
),
root.createComponent(
View,
{border: 'base', padding: 'base'},
'auto / 300',
),
root.createComponent(GridItem, {columnSpan: 2}, [
root.createComponent(
View,
{border: 'base', padding: 'base'},
'20% + fill / auto',
),
]),
root.createComponent(
View,
{border: 'base', padding: 'base'},
'auto / auto',
),
],
);

root.appendChild(grid);
});

  • Only use GridItem inside a Grid: GridItem is designed as a direct child of Grid. Using it elsewhere has no effect.
  • Set explicit spans: Use columnSpan and rowSpan to control how many cells the item occupies. Without explicit spans, the item occupies a single cell.
  • Use for intentional layout overrides: Reserve GridItem for elements that need non-default positioning. Regular Grid children flow automatically.

  • GridItem can be used only as a direct child of Grid. It has no effect outside a grid context.
  • Spanning uses columnSpan and rowSpan as numbers, not CSS grid syntax like span 2.
  • GridItem can't be positioned at arbitrary grid coordinates. It only controls span size, not starting position.
