Example

Check full example in the Example folder.

import React, { Component } from 'react-native';
import Accordion from 'react-native-collapsible/Accordion';
 
const SECTIONS = [
  {
    title: 'First',
    content: 'Lorem ipsum...',
  },
  {
    title: 'Second',
    content: 'Lorem ipsum...',
  }
];
 
class AccordionView extends Component {
  _renderHeader(section) {
    return (
      <View style={styles.header}>
        <Text style={styles.headerText}>{section.title}</Text>
      </View>
    );
  }
 
  _renderContent(section) {
    return (
      <View style={styles.content}>
        <Text>{section.content}</Text>
      </View>
    );
  }
 
  render {
    return (
      <Accordion
        sections={SECTIONS}
        renderHeader={this._renderHeader}
        renderContent={this._renderContent}
      />
    );
  }
}

Transition backgrounds

If you combine with the react-native-animatable library you can easily transition the background color between the active and inactive state or add animations.

Lets augment the example above with:

import * as Animatable from 'react-native-animatable';
 
(...)
 
  _renderHeader(section, index, isActive) {
    return (
      <Animatable.View
        style={styles.header}
        duration={300}
        transition="backgroundColor"
        style={{ backgroundColor: (isActive ? 'rgba(255,255,255,1)' : 'rgba(245,252,255,1)') }}>
        <Text style={styles.headerText}>{section.title}</Text>
      </Animatable.View>
    );
  }
 
  _renderContent(section, i, isActive) {
    return (
      <Animatable.View
        style={styles.content}
        duration={300}
        transition="backgroundColor"
        style={{ backgroundColor: (isActive ? 'rgba(255,255,255,1)' : 'rgba(245,252,255,1)') }}>
        <Animatable.Text
          duration={300}
          easing="ease-out"
          animation={isActive ? 'zoomIn' : false}>
          {section.content}
        </Animatable.Text>
      </Animatable.View>
    );
  }
 
(...)
