Grid

A multi-column grid that wraps children into equal-width columns. Built on top of Row, so all Box spacing and alignment props are available.

Usage

import { Card, Grid, Typography } from '@rootnative/components'
import { ThemeProvider } from '@rootnative/core'
import { SafeAreaProvider } from 'react-native-safe-area-context'
import { View } from 'react-native'

export default function App() {
  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center', padding: 16 }}>
          <Grid columns={2} gap="sm">
            <Card variant="outlined"><Typography>Item 1</Typography></Card>
            <Card variant="outlined"><Typography>Item 2</Typography></Card>
            <Card variant="outlined"><Typography>Item 3</Typography></Card>
            <Card variant="outlined"><Typography>Item 4</Typography></Card>
          </Grid>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

How It Works

Each child is wrapped in a cell with flexBasis: ${100 / columns}%, so all columns are equal width. The gap prop is implemented as gutters rather than by shrinking cells: each cell takes half the gap as horizontal padding, and the row cancels the outer half on both edges with a negative margin. flexBasis stays exactly 100 / columns%, so the row occupies the full width of its parent and the outermost cells stay flush with its edges.

Different Column Counts

import { Button, Grid, IconButton, Typography } from '@rootnative/components'
import { ThemeProvider } from '@rootnative/core'
import { SafeAreaProvider } from 'react-native-safe-area-context'
import { View } from 'react-native'

export default function App() {
  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center', padding: 16, gap: 24 }}>
          <Typography variant="titleSmall">Two columns</Typography>
          <Grid columns={2} gap="md">
            <Button variant="filled" onPress={() => {}}>A</Button>
            <Button variant="outlined" onPress={() => {}}>B</Button>
          </Grid>
          <Typography variant="titleSmall">Four columns</Typography>
          <Grid columns={4} gap="sm">
            <IconButton icon="heart" accessibilityLabel="Heart" onPress={() => {}} />
            <IconButton icon="star" accessibilityLabel="Star" onPress={() => {}} />
            <IconButton icon="bell" accessibilityLabel="Bell" onPress={() => {}} />
            <IconButton icon="cog" accessibilityLabel="Settings" onPress={() => {}} />
          </Grid>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

Responsive Columns

columns also accepts a map of window size classes. The grid re-resolves the count when the window crosses a breakpoint. A map cascades down to the nearest smaller breakpoint, so you only set the widths where the count changes.

import { Card, Grid, Typography } from '@rootnative/components'
import { ThemeProvider } from '@rootnative/core'
import { SafeAreaProvider } from 'react-native-safe-area-context'
import { View } from 'react-native'

export default function App() {
  return (
    <SafeAreaProvider>
      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center', padding: 16 }}>
          <Grid columns={{ compact: 1, medium: 2, expanded: 4 }} gap="sm">
            <Card variant="outlined"><Typography>Item 1</Typography></Card>
            <Card variant="outlined"><Typography>Item 2</Typography></Card>
            <Card variant="outlined"><Typography>Item 3</Typography></Card>
            <Card variant="outlined"><Typography>Item 4</Typography></Card>
          </Grid>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

The map requires a compact key, so every width resolves to a value. Use useBreakpointValue from @rootnative/core directly when a value other than the column count must follow the same breakpoints.

Spanning Cells

A plain child always spans one column. Wrap a child in Grid.Cell to make it span more, for asymmetric layouts such as a main area with a sidebar. The span prop also accepts a breakpoint map, and an oversized span is clamped to the column count, so it fills the row instead of overflowing it.

      <ThemeProvider>
        <View style={{ flex: 1, justifyContent: 'center', padding: 16 }}>
          <Grid columns={12} gap="sm">
            <Grid.Cell span={8}>
              <Card variant="outlined"><Typography>Main</Typography></Card>
            </Grid.Cell>
            <Grid.Cell span={4}>
              <Card variant="outlined"><Typography>Aside</Typography></Card>
            </Grid.Cell>
            <Grid.Cell span={{ compact: 12, medium: 6 }}>
              <Card variant="outlined"><Typography>Half on tablets</Typography></Card>
            </Grid.Cell>
          </Grid>
        </View>
      </ThemeProvider>
    </SafeAreaProvider>
  )
}

Grid.Cell is also exported as GridCell for direct imports. It only sizes itself inside a Grid — rendered anywhere else it warns in development and falls back to full width.

Props

Prop	Type	Default	Required	Description
columns	number | BreakpointValues<number>	-	Yes	Number of equal-width columns, or a breakpoint map of column counts. A map cascades down to the nearest smaller breakpoint, so `{ compact: 1, expanded: 4 }` gives 1 column below 840dp and 4 at or above.
wrap	boolean	false	No	Whether children should wrap to the next line when they overflow.
inverted	boolean	false	No	Reverses the layout direction (`row-reverse`).
p	SpacingValue	-	No	Padding on all sides
px	SpacingValue	-	No	Horizontal padding (paddingStart + paddingEnd)
py	SpacingValue	-	No	Vertical padding (paddingTop + paddingBottom)
pt	SpacingValue	-	No	Padding top
pb	SpacingValue	-	No	Padding bottom
ps	SpacingValue	-	No	Padding start (left in LTR, right in RTL)
pe	SpacingValue	-	No	Padding end (right in LTR, left in RTL)
m	SpacingValue	-	No	Margin on all sides
mx	SpacingValue	-	No	Horizontal margin (marginStart + marginEnd)
my	SpacingValue	-	No	Vertical margin (marginTop + marginBottom)
mt	SpacingValue	-	No	Margin top
mb	SpacingValue	-	No	Margin bottom
ms	SpacingValue	-	No	Margin start
me	SpacingValue	-	No	Margin end
gap	SpacingValue	-	No	Gap between children
rowGap	SpacingValue	-	No	Row gap between children
columnGap	SpacingValue	-	No	Column gap between children
flex	number	-	No	Flex value

justify	enum	-	No	Justify content along the main axis
bg	string	-	No	Background color
onKeyDown	(event: { nativeEvent: { key?: string; }; }) => void	-	No	-

Grid.Cell

Prop	Type	Default	Required	Description
span	number | BreakpointValues<number>	1	No	Number of grid columns this cell spans, or a breakpoint map of spans. Clamped to the parent Grid's column count, so an oversized span fills the row instead of overflowing it.
onKeyDown	(event: { nativeEvent: { key?: string; }; }) => void	-	No	-
