react-native-accordion-list-view

A high performance, beautiful and fully customizable Accordion list for React Native. Implemented using react-native-vector-icons.

Getting started

npm install react-native-accordion-list-view --save

yarn add react-native-accordion-list-view

Now we need to install react-native-vector-icons.

npm install react-native-vector-icons --save

yarn add react-native-vector-icons

Platforms Supported

[x] iOS
[x] Android

Important Note

This plugin work with Layout Animation and In order to get this to work on Android you need to set the following flags via UIManager:

if (Platform.OS === 'android') {
    if (UIManager.setLayoutAnimationEnabledExperimental) {
        UIManager.setLayoutAnimationEnabledExperimental(true);
    }
}

Demo

## Versioning This project follows semantic versioning. We do not hesitate to release breaking changes but they will be in a major version.

Breaking History:

2.0.3 - New Features We've enhanced the Accordion list by adding support for the index parameter in the customTitle, customBody, and customIcon functions. This enables greater customization possibilities, allowing you to dynamically adjust the rendering of elements based on the index of each accordion item. Explore these new parameters to tailor your accordion items more precisely to your application's requirements.
2.0.2 - New Features

defaultOpenIndices: You can now specify an array of indices in the defaultOpenIndices prop for the accordion list. These indices indicate which sections should be expanded by default, allowing you to control the initial state of the accordion.

pressableProps: We've added a new prop called pressableProps to both the accordion list and accordion item components. This allows you to customize the styles and ripple effects for the pressable component, giving you more control over the user interaction experience.
2.0.1 - Allow single/multiple expanding, allow AccordionItem to be opened by default using isOpen property, add onPress for AccordionItem.
2.0.0 - Change library code to typescript and Replacing TouchableOpacity with Pressable.
1.0.4 - Support RTL and update README.
1.0.3 - Accordion list FlatList props bug fixes.
1.0.2 - Accordion Item Bug fixes.
1.0.1 - Update README.
1.0.0 - First release.

More props

This is a wrapper around Flatlist, all their props works well and the inherited props too (from ScrollView and VirtualizedList).

Common Issues and Errors

Error: You have multiple items opened by default, but expandMultiple is disabled, If you encounter the following error message in your console:

console.error('Error: You have multiple items opened by default, but expandMultiple is disabled.');

This error occurs when you have set expandMultiple to false and provided an array with multiple indices in the defaultOpenIndices prop. Remember that when expandMultiple is set to false, you can only specify a single index in the defaultOpenIndices array.

To resolve this issue, make sure that defaultOpenIndices contains only one index when expandMultiple is false.
