Multiline textarea input field is required where a lengthy text needs to be entered. Some use case are About me field in profile, chat messenger box, wysiwyg editor etc.
React native provides multiline
and numberOfLines
props for <TextInput>
component which can create a textarea.
Code Example
import React from "react"; import { SafeAreaView, StyleSheet, TextInput, Text, View } from "react-native"; const MultilineTextInput = () => { const [text1, onChangeText1] = React.useState(""); return ( <SafeAreaView> <View style={styles.container}> <TextInput style={styles.input} onChangeText={onChangeText1} value={text1} multiline={true} numberOfLines={6} textAlignVertical={'top'} /> </View> </SafeAreaView> ); }; const styles = StyleSheet.create({ container: { marginTop: 40, }, input: { margin: 12, borderWidth: 1, padding: 10, }, }); export default MultilineTextInput;
output –
The above image is of iOS (left) and Android (right) mobiles. It shows how multiline input field looks like on both types of operating systems. In iOS the input field expands with new line but we can fix the height in Android.
In the code, you can see few things –
- We used
multiline
prop in line 14 to indicate that input field will not submit the form on press of return key and new line will generate. -
numberOfLines
prop in line 15, works in Android only. This provides a predefined height to the input box. -
textAlignVertical
is another prop for Android. This is because, by default, android place the cursor at the middle of the text input. To start typing from top, we are setting this prop and providing value top.

Conclusion
In React Native, you can create multiline text input using multiline
prop. To better utilize this prop, use it with numberOfLines
prop in Android version.
