• SplitView: Root container that manages snap points, drag state, and layout. Exposes layout state and snap controls via useSplitView and render props.
• SplitView.TopSection: Top pane with animated height driven by drag and snap state. Content should scroll internally when it exceeds the current height.
• SplitView.DragArea: Pan gesture hit region with an extended touch target. Typically wraps SplitView.DragHandle.
• SplitView.DragHandle: Visual pill handle. Scales slightly while dragging when animations are enabled.
• SplitView.BottomSection: Bottom pane that fills remaining space below the drag area.

Usage

Basic usage

The SplitView uses compound parts to build a vertical split layout with a draggable divider.

<SplitView>
  <SplitView.TopSection>...</SplitView.TopSection>
  <SplitView.DragArea>
    <SplitView.DragHandle />
  </SplitView.DragArea>
  <SplitView.BottomSection>...</SplitView.BottomSection>
</SplitView>

Custom snap points

Pass snapPoints as ratios of container height (0..1) or absolute px (> 1). Combine with defaultSnapIndex and minHeight for uncontrolled layouts.

<SplitView snapPoints={[150, 0.5, 0.75]} defaultSnapIndex={1} minHeight={50}>
  <SplitView.TopSection>...</SplitView.TopSection>
  <SplitView.DragArea>
    <SplitView.DragHandle />
  </SplitView.DragArea>
  <SplitView.BottomSection>...</SplitView.BottomSection>
</SplitView>

Skip initial animation

By default (skipInitialAnimation is true) the divider appears already positioned at its starting snap point instead of animating into place on mount or screen focus. Subsequent snaps and drags still animate. Set skipInitialAnimation={false} to animate the divider into place on first render.

<SplitView skipInitialAnimation={false}>
  <SplitView.TopSection>...</SplitView.TopSection>
  <SplitView.DragArea>
    <SplitView.DragHandle />
  </SplitView.DragArea>
  <SplitView.BottomSection>...</SplitView.BottomSection>
</SplitView>

Controlled snap index

Control the active snap index externally with snapIndex and onSnapIndexChange.

const [snapIndex, setSnapIndex] = useState(1);

<SplitView snapIndex={snapIndex} onSnapIndexChange={setSnapIndex}>
  <SplitView.TopSection>...</SplitView.TopSection>
  <SplitView.DragArea>
    <SplitView.DragHandle />
  </SplitView.DragArea>
  <SplitView.BottomSection>...</SplitView.BottomSection>
</SplitView>;

Render function children

Use a render function to read layout state and drive animations inside children.

<SplitView>
  {({ topSectionHeight, minPx, maxPx }) => (
    <>
      <SplitView.TopSection>...</SplitView.TopSection>
      <SplitView.DragArea>
        <SplitView.DragHandle />
      </SplitView.DragArea>
      <SplitView.BottomSection>...</SplitView.BottomSection>
    </>
  )}
</SplitView>

Accessing context from children

Use the useSplitView hook inside any descendant to read animated layout values and trigger snap transitions.

const { topSectionHeight, minPx, snapTo } = useSplitView();

Disabled animation

Disable all animations for the subtree with animation="disable-all".

<SplitView animation="disable-all">
  <SplitView.TopSection>...</SplitView.TopSection>
  <SplitView.DragArea>
    <SplitView.DragHandle />
  </SplitView.DragArea>
  <SplitView.BottomSection>...</SplitView.BottomSection>
</SplitView>

Example

import { SplitView } from 'heroui-native-pro';
import { Text, View } from 'react-native';

export default function SplitViewExample() {
  return (
    <View className="flex-1 px-5 justify-center">
      <View
        className="h-3/5 w-full p-2 rounded-4xl overflow-hidden bg-surface-secondary"
        style={{ borderCurve: 'continuous' }}
      >
        <SplitView minHeight={50} maxHeight={1}>
          <SplitView.TopSection>
            <View
              className="flex-1 items-center justify-center p-4 bg-surface rounded-3xl"
              style={{ borderCurve: 'continuous' }}
            >
              <Text className="text-foreground">
                Top section — drag the handle to resize.
              </Text>
            </View>
          </SplitView.TopSection>
          <SplitView.DragArea className="h-5">
            <SplitView.DragHandle />
          </SplitView.DragArea>
          <SplitView.BottomSection>
            <View
              className="flex-1 items-center justify-center p-4 bg-surface rounded-3xl"
              style={{ borderCurve: 'continuous' }}
            >
              <Text className="text-foreground">
                Bottom section fills remaining space.
              </Text>
            </View>
          </SplitView.BottomSection>
        </SplitView>
