Components
CollapseHeader & CollapseBody
Think about CollapseHeader and CollapseBody as a View that you can style it as you want.
When you touch the header it will show or hide the body.
Collapse
You need to wrap a CollapseHeader & a CollapseBody in the Collapse.
Props Name Default Type Description
isCollapsed false boolean show the CollapseBody if true
disabled false boolean disable the click on the collapse header if true
onToggle ()=>undefined Function(isCollapsed:boolean) onToggle is a function take in input a boolean value that contains the state of the Collapse (if collapsed->true)
handleLongPress undefined Function() handles the onLongPress event when longPressing on the collapseHeader content
In case you want to use and change the state of the Collapse in the parent, You can use isCollapsed & onToggle as an input & output to synchronise the parent collapse state & the child (Collapse) state.
Example of use
You can control & use the state collapse of the Collapse in you're component as shown down below:
  import React, { Component } from 'react';
  import{ View,Text,Button } from 'react-native';
  import {Collapse, CollapseHeader, CollapseBody} from "accordion-collapse-react-native";
  
class Example extends Component<>{ 
constructor(props){
    super(props);
    this.state = {
    collapsed:false,//do not show the body by default
    }
}
render(){
    return (
    <View>
	    <Button 
		    title={"Click here too"} 
		    onPress={()=>this.setState({collapsed:!this.state.collapsed})}
	    />
        <Collapse 
	        isCollapsed={this.state.collapsed} 
	        onToggle={(isCollapsed)=>this.setState({collapsed:isCollapsed})}>
          <CollapseHeader>
            <Text>Click here</Text>
          </CollapseHeader>
          <CollapseBody>
            <Text>WHoooHo!</Text>
          </CollapseBody>
        </Collapse>
      </View>
      );
      }
}
AccordionList
AccordionList components allow you to show an accordion with list of sections (head&body)
