React Native Collapsible Tab View is a versatile library for creating collapsible tab views using Reanimated.

• Explore the examples for the source code of the Expo app.

The react-native-tab-view example app was used as a template for the demos.

Default	Snap	revealHeaderOnScroll	revealHeaderOnScroll + Snap

• UI thread animations and interactions
• High customizability
• Full TypeScript support
• Lazy loading with fade-in animation
• DiffClamp header
• Interpolated header
• Scroll snap (with interpolated header)
• Animated snap (with diffClamp header)
• Scrollable tabs, inspired by the react-native-tab-view tab bar

To install the library, open a terminal in your project's root directory and run:

yarn add react-native-collapsible-tab-view react-native-pager-view

Then, add Reanimated, follow the official installation guide.

import React from 'react'
import { View, StyleSheet, ListRenderItem } from 'react-native'
import { Tabs } from 'react-native-collapsible-tab-view'

const HEADER_HEIGHT = 250

const DATA = [0, 1, 2, 3, 4]
const identity = (v: unknown): string => v + ''

const Header = () => {
  return <View style={styles.header} />
}

const Example: React.FC = () => {
  const renderItem: ListRenderItem<number> = React.useCallback(({ index }) => {
    return (
      <View style={[styles.box, index % 2 === 0 ? styles.boxB : styles.boxA]} />
    )
  }, [])

  return (
    <Tabs.Container
      renderHeader={Header}
      headerHeight={HEADER_HEIGHT} // optional
    >
      <Tabs.Tab name="A">
        <Tabs.FlatList
          data={DATA}
          renderItem={renderItem}
          keyExtractor={identity}
        />
      </Tabs.Tab>
      <Tabs.Tab name="B">
        <Tabs.ScrollView>
          <View style={[styles.box, styles.boxA]} />
          <View style={[styles.box, styles.boxB]} />
        </Tabs.ScrollView>
      </Tabs.Tab>
    </Tabs.Container>
  )
}

const styles = StyleSheet.create({
  box: {
    height: 250,
    width: '100%',
  },
  boxA: {
    backgroundColor: 'white',
  },
  boxB: {
    backgroundColor: '#D8D8D8',
  },
  header: {
    height: HEADER_HEIGHT,
    width: '100%',
    backgroundColor: '#2196f3',
  },
})

export default Example

To enable scrolling from the header, follow these steps:

• If the HeaderComponent does not contain touchable components, set the pointerEvents prop to 'none'.
• If the HeaderComponent does contain touchable components, set the pointerEvents prop to 'box-none' to ensure they function properly.

Note: If any child component within the HeaderComponent should not respond to touches, such as an <Image /> element, set its pointerEvents prop to 'none'. Otherwise, it may unintentionally become the target of a touch gesture on iOS devices and prevent scrolling.

Basic usage looks like this:

import { Tabs } from 'react-native-collapsible-tab-view'

const Example = () => {
   return (
     <Tabs.Container renderHeader={MyHeader}>
       <Tabs.Tab name="A">
         <ScreenA />
       </Tabs.Tab>
       <Tabs.Tab name="B">
         <ScreenB />
       </Tabs.Tab>
     </Tabs.Container>
   )
}

Wrap your screens with Tabs.Tab. Basic usage looks like this:

<Tabs.Container ...>
  <Tabs.Tab name="A" label="First Tab">
   <ScreenA />
  </Tabs.Tab>
  <Tabs.Tab name="B">
   <ScreenA />
  </Tabs.Tab>
</Tabs.Container>

Typically used internally, but if you want to mix lazy and regular screens you can wrap the lazy ones with this component.

Use like a regular FlatList.

Use like a regular FlashList.

Use like a regular MasonryFlashList.

Use like a regular ScrollView.

Use like a regular SectionList.

You can pass a ref to Tabs.Container.

const ref = React.useRef()
<Tabs.Container ref={ref}>

This hook provides access to key styles for the collapsible tab view. It can be used to obtain the progressViewOffset and pass it to the RefreshControl of the scroll view.

const {
  contentContainerStyle,
  progressViewOffset,
  style,
} = useCollapsibleStyle()

This hook returns an animated value representing the current tab index. As the tab view can be in between panes while swiping, this value is a floating-point number.

const tabIndex = useAnimatedTabIndex()

This hook returns the name of the currently focused tab.

const focusedTab = useFocusedTab()

This hook returns the top distance and the header height. For an example of how to use this, check out the animated header example in the example folder.

const { top, height } = useHeaderMeasurements()

This hook returns the vertical scroll position of the current tab as an Animated SharedValue.

Since this library requires handling the onScroll event for its functionality, this is the only way to react to changes in the scroll position of the underlying scrollable component.

const scrollY = useCurrentTabScrollY()

Any additional props are passed to the pressable component.

Refer to this open issue. We utilize scrollTo to synchronize the unfocused tabs. While it is intended for use with ScrollView, it works well with FlatList, until the RefreshControl is added. Note that this issue occurs only on Android.

Workaround: Check out the Android Shared Pull To Refresh example in the expo app. You can implement a single pull-to-refresh for the Tabs.Container.

When using the stickyHeaderIndices prop on a FlatList or stickySectionHeadersEnabled on a SectionList, the sticky elements do not scroll up as the header collapses. This issue is specific to iOS.

See #136.

This is not an issue per se, but it's essential to be aware of it. When using containerRef.current.setIndex(i), if you set it to the current index, the screen will scroll to the top. You can prevent this behavior as follows:

const index = pageRef.current?.getCurrentIndex()
if (index !== nextIndex) {
  pageRef.current?.setIndex(nextIndex)
}

If you do not require a full-featured tab view, consider another option: a simple segmented control / material tab bar without swiping or snapping, using only the React Native Animated API.
