I am using reanimated 2 for animation. So you should install and follow instruction here to setup your project react-native-reanimated

Key features

1️⃣ Support FlatList/ScrollView 2️⃣ Support sticky header 3️⃣ Can have multiple sticky headers 4️⃣ Easy to customize

Usage

1. Basic

import {
  CollapsibleContainer,
  CollapsibleFlatList,
  CollapsibleScrollView,
} from '@r0b0t3d/react-native-collapsible';

// ...
const MyComponent = () => {
  const {
    collapse,   // <-- Collapse header
    expand,     // <-- Expand header
    scrollY,    // <-- Animated scroll position. In case you need to do some animation in your header or somewhere else
  } = useCollapsibleContext();

  return (
    <CollapsibleContainer>          // 1️⃣ (Required) Outermost container 
      <CollapsibleHeaderContainer>  // 2️⃣ (Required) Header view
        <!-- Your header view -->
        <StickyView>                // 3️⃣ Sticky view
          <!-- Your sticky view goes here -->
        </StickyView>
      </CollapsibleHeaderContainer>
      <CollapsibleFlatList          // 4️⃣ (Required) Your FlatList/ScrollView
        data={data}
        renderItem={renderItem}
        headerSnappable={false} // <-- should header auto snap when you release the finger
      />
    </CollapsibleContainer>
  )
}

export default withCollapsibleContext(MyComponent); // 5️⃣ (Required)wrap your component with `withCollapsibleContext`

2. Advance

We support multiple CollapsibleHeaderContainer and StickyView. It come useful in case you need to break your code into smaller component.

Parent.tsx

const Parent = () => {
  const [tabIndex, setTabIndex] = useState(0)

  return (
    <CollapsibleContainer>
      <CollapsibleHeaderContainer>
        <!-- Your header view -->
        <StickyView>
          <TabView currentTab={tabIndex} onTabChange={setTabIndex} />
        </StickyView>
      </CollapsibleHeaderContainer>

      {tabIndex === 0 && <FirstTab />}
      {tabIndex === 1 && <SecondTab />}
    </CollapsibleContainer>
  )
}

FirstTab.tsx

const FirstTab = () => {
  return (
    <>
      <CollapsibleHeaderContainer>
        <!-- 😍 You can have another headerview in each tab where you can add another StickyView there -->
        <StickyView>
          <!-- Your sticky view goes here -->
        </StickyView>
        <View />
        <StickyView>
          <!-- 🚀 Bonus, multiple sticky view -->
        </StickyView>
      </CollapsibleHeaderContainer>
      <CollapsibleFlatList
        data={data}
        renderItem={renderItem}
      />
    </>
  )
}

Tips

1. Trigger scroll when scroll inside CollapsibleHeaderContainer

• If your header doesn't contains touchable component, try pointerEvents="none"

<CollapsibleHeaderContainer>
  <View pointerEvents="none">
    <Text>Header</Text>
  </View>
</CollapsibleHeaderContainer>

• If your header contains touchable componet, try to set pointerEvents="box-none" for every nested views that contains touchable, otherwise use pointerEvents="none"

<CollapsibleHeaderContainer>
    <View pointerEvents="box-none"> // <-- this is parent view
        <View pointerEvents="none"> // <-- this view doesn't contain touchable component
            <Text>Header</Text>
        </View>
        <View pointerEvents="box-none"> // <-- this view contain touchable component
            <View pointerEvents="none">
                <Text>Some text</Text>
            </View>
            <TouchableOpacity>
                <Text>Button</Text>
            </TouchableOpacity>
        </View>
    </View>
</CollapsibleHeaderContainer>
