# Keyboard Scroll View

A scroll view that keeps the focused text field visible above the on-screen keyboard.

Keyboard Scroll View is an open-source mobile component from suiss/uim for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.

```tsx

      <Input placeholder={label} />

      <Text variant="h3">Shipping address</Text>
      <Fields />
    </KeyboardScrollView>
  )
}
```

```swift
import EsuissUI
import SwiftUI

  var body: some View {
    KeyboardScrollView {
      VStack(alignment: .leading, spacing: 16) {

import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.PaddingValues
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier

fun KeyboardScrollViewDefault() {
    Screen {
        KeyboardScrollView(
            modifier = Modifier.fillMaxSize(),
            contentPadding = PaddingValues(16.dp),
            verticalArrangement = Arrangement.spacedBy(16.dp),
        ) {
            Text("Shipping address", variant = TextVariant.H3)
            KeyboardScrollViewFields()
        }
    }
}
```

`KeyboardScrollView` wraps the React Native `ScrollView`. When the keyboard opens, it measures how much of the view the keyboard covers, adds matching space at the end of the content and scroll indicator, and scrolls just enough to bring the focused input above the keyboard.

Use it for forms and other screens with text fields that would otherwise end up behind the keyboard.

### Manual

**Uniwind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install cn
```

2. Add the pieces it builds on: the primitives `components/primitives/hooks.tsx`, `components/primitives/keyboard.tsx`.

3. Copy the source into `components/ui/keyboard-scroll-view.tsx`:

```tsx title="uniwind/components/ui/keyboard-scroll-view.tsx"

3. Update the import paths to match your project.

**SwiftUI**

1. Target iOS 17 or later.

2. Copy the theme files every view uses:

```swift title="swift/Theme/Theme.swift"

3. Copy the source:

4. Add the files to your app target.

**Jetpack Compose**

1. Set `minSdk` to 24 or higher and add the dependencies:

```kotlin title="build.gradle.kts"
implementation(platform("androidx.compose:compose-bom:2026.09.00"))
implementation("androidx.compose.foundation:foundation")
implementation("androidx.compose.ui:ui")
```

2. Copy the theme files every view uses:

4. Update the `com.esuiss.ui` package names to match your project.

## Usage

```tsx
import { KeyboardScrollView } from "@/components/ui/keyboard-scroll-view"
```

```tsx
<KeyboardScrollView className="-m-4" contentContainerClassName="gap-4 p-4">
  <Text variant="h3">Shipping address</Text>
  <Fields />
</KeyboardScrollView>
```

Place inputs anywhere inside the view; no extra setup is needed. Set `bottomOffset` to leave more space between the focused field and the keyboard.

All `ScrollView` props are passed through. By default taps on the content are handled while the keyboard is open (`keyboardShouldPersistTaps="handled"`), and dragging dismisses the keyboard.

`KeyboardScrollViewContext` exposes `scrollToFocused`, which children can call to bring the focused input into view again, for example after their layout changes.

## Examples

### Larger bottom offset

Keeps the focused field 64 points above the keyboard.

```tsx
import { View } from "react-native"
import { Input } from "@/components/ui/input"
import { KeyboardScrollView } from "@/components/ui/keyboard-scroll-view"
import { Text } from "@/components/ui/text"

const fields = [
  "First name",
  "Last name",
  "Email",
  "Phone",
  "Street",
  "City",
  "Postal code",
  "Country",
  "Company",
  "Notes",
]

function Fields() {
  return fields.map((label) => (
    <View key={label} className="gap-1.5">
      <Text variant="small">{label}</Text>
      <Input placeholder={label} />
    </View>
  ))
}

export function KeyboardScrollViewLargerBottomOffsetExample() {
  return (
    <KeyboardScrollView
      bottomOffset={64}
      className="-m-4"
      contentContainerClassName="gap-4 p-4"
    >
      <Text variant="h3">64 pt above the keyboard</Text>
      <Fields />
    </KeyboardScrollView>
  )
}
```

### Focused

The last field is focused on mount and scrolled into view.

## API Reference

### KeyboardScrollView

## Accessibility

- The view is a standard `ScrollView`, so screen reader scrolling works as usual.

## Notes

- `keyboardDismissMode` defaults to `interactive` on iOS and `on-drag` on Android.
- After a touch while the keyboard is open, the view checks the focused input again after a short delay.
- The view fills its parent with `flex-1`.
- Only an input that is inside the visible frame of the scroll view is adjusted; inputs scrolled out of view are left alone.
