Example to make Section List in React Native

Section List in React Native

This is an example to make Section List in React Native. Section List is a list of sections and headings. It is among the simple but mostly used components. This example will be helpful for you to understand how to use Section List in React Native. You can also check FlatList example for the Simple list.

To Import Section List in React Native Code

import {SectionList} from 'react-native'

Render Using

   ItemSeparatorComponent={Separator View} 
   sections={Section Data} 
   renderSectionHeader={({ section }) => (Header View)} 
   renderItem={({ item }) => (Single Item View)} 
   keyExtractor={(item, index) => index} 

In this example, we will make a list of country names with the header of their initials. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.


Open App.js in any code editor and replace the code with the following code


// Example to make Section List in React Native
// https://aboutreact.com/react-native-sectionlist/

// import React in our code
import React from 'react';

// import all the components we are going to use
import {
} from 'react-native';

const App = () => {
  let A = [
    {id: '1', value: 'Afghanistan'},
    {id: '2', value: 'Afghanistan'},
    {id: '3', value: 'Afghanistan'},
  let B = [
    {id: '4', value: 'Benin'},
    {id: '5', value: 'Bhutan'},
    {id: '6', value: 'Bosnia'},
    {id: '7', value: 'Botswana'},
    {id: '8', value: 'Brazil'},
    {id: '9', value: 'Brunei'},
    {id: '10', value: 'Bulgaria'},
  let C = [
    {id: '11', value: 'Cambodia'},
    {id: '12', value: 'Cameroon'},
    {id: '13', value: 'Canada'},
    {id: '14', value: 'Cabo'},

  const FlatListItemSeparator = () => {
    return (
      //Item Separator
      <View style={styles.listItemSeparatorStyle} />

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
            {title: 'Section Head For Data A', data: A},
            {title: 'Section Head For Data B', data: B},
            {title: 'Section Head For Data C', data: C},
          renderSectionHeader={({section}) => (
            <Text style={styles.sectionHeaderStyle}>
          renderItem={({item}) => (
            // Item for the FlatListItems
              //Item Separator View
              onPress={() => alert(JSON.stringify(item))}>
          keyExtractor={(item, index) => index}

export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    backgroundColor: 'white',
  sectionHeaderStyle: {
    backgroundColor: '#CDDC89',
    fontSize: 20,
    padding: 5,
    color: '#fff',
  sectionListItemStyle: {
    fontSize: 15,
    padding: 15,
    color: '#000',
    backgroundColor: '#F5F5F5',
  listItemSeparatorStyle: {
    height: 0.5,
    width: '100%',
    backgroundColor: '#C8C8C8',

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

To run the project on an Android Virtual Device or on real debugging device

react-native run-android

or on the iOS Simulator by running (macOS only)

react-native run-ios
