# react-native-multiselect

> A simple RN component that allows row selection



## Install

`yarn add react-native-multiselect` or `npm install react-native-multiselect --save`



### 3.0.0

`3.0.0` swaps out `ListView` for `FlatList` or `SectionList`. This gives a huge performance increase for larger lists. This is a **breaking change** so you might need to modify your implementation of `react-native-multiselect` for this to work. Don't worry though, its not a massive change.



### 2.0.0

**If you used `<2.0.0` the `renderRow` API has changed and you'll need to do a small rewrite**



`2.0.0` brings some major performance enhancements and removes the dependancy on `react-native-vector-icons`, you are now just given an `isSelected` parameter which you can use to style the `renderRow`. Thanks to [@indesignlatam](https://github.com/indesignlatam) for proposing a fix to performance issues with large datasets.



## API

### `options[]` `required`

An array of values for the list to display. Each item in the array should be an

object that looks like this:

```javascript

{

  // A unique identifier for the row

  key: Number || String

  // The name displayed in the row

  name: String

  // This namespace can also be used to store custom props

  ...customProps

}

```



### `renderRow` `(row, isSelected)` `required`

A function that renders each row. The current row object is passed to it to

allow dynamic rows. This is where you could use the `customProps` mentioned

above. You can use the `isSelected` parameter to decide how to style your row when its selected



### `onSelectionChange` `(selectedRow, allSelectedRows)`

A callback that is fired when a row is clicked. It is passed the row that was

just selected as well as an array of all the currently selected rowStyle.



### `selectedOptions[]`

An array of `keys` that match those in `options` that will be preselected on the

list.



### `rowStyle{}`

A React Native style object, you can also pass StyleSheet styles to this; they

will be flattened.



### `listProps{}`

An object of props that are given to the FlatList or SectionList, this for things like `ListHeaderComponent`



### `activeOpacity` `Number`

Proxied to the TouchableHighlight component when you click the row



### `underlayColor` `String`

Proxied to the TouchableHighlight component when you click the row



### `useSections` `Boolean`

Use this to render a `SectionList` instead of a `FlatList`. Your `options` prop needs to looks like the one seen here: https://facebook.github.io/react-native/docs/sectionlist.html



## Usage

```javascript

import MultiSelect from 'react-native-multiselect';



const MyComponent = ({

  // [{id: 1, name: 'Thing 1', data: [...]}, {id: 2, name: 'Thing 2', data: [...]} ...]

  listOfThings,

  // [0, 4]

  preselectedThings,

  // (selectedRows) => this.setState({ selectedRows })

  updateListOfSelectedThings,

}) => (

  

    Select some items from the list

     ({ key: thing.id, name: thing.name }) )}

      renderRow={(row, isSelected) => {row.name} {isSelected ? 'I am selected' : 'I am not selected'}}

      onSelectionChange={

        (selectedRow, allSelectedRows) => updateListOfSelectedThings(allSelectedRows)

      }

      selectedOptions={[]}

      rowStyle={{ backgroundColor: 'skyblue' }}

    />

  

);

```
