Simple multi-select component for react-native (Select2 for react-native).
I've been super busy with work and other projects lately that I really don't have enough time to dedicate to this project. If you would like to maintain this project, you can drop me an email. Thanks.
$ npm install react-native-multiple-select --saveor use yarn
$ yarn add react-native-multiple-selectNote: Ensure to add and configure react-native-vector-icons to your project before using this package.
You can clone and try out the sample app.
The snippet below shows how the component can be used
// import component
import React, { Component } from 'react';
import { View } from 'react-native';
import MultiSelect from 'react-native-multiple-select';
class MultiSelectExample extends Component {
this.state = {
selectedItems = [];
};
this.items = [{
id: '92iijs7yta',
name: 'Ondo',
}, {
id: 'a0s0a8ssbsd',
name: 'Ogun',
}, {
id: '16hbajsabsd',
name: 'Calabar',
}, {
id: 'nahs75a5sg',
name: 'Lagos',
}, {
id: '667atsas',
name: 'Maiduguri',
}, {
id: 'hsyasajs',
name: 'Anambra',
}, {
id: 'djsjudksjd',
name: 'Benue',
}, {
id: 'sdhyaysdj',
name: 'Kaduna',
}, {
id: 'suudydjsjd',
name: 'Abuja',
}];
onSelectedItemsChange = selectedItems => {
this.setState({ selectedItems });
};
render() {
const { selectedItems } = this.state;
return (
<View style={{ flex: 1 }}>
<MultiSelect
hideTags
items={items}
uniqueKey="id"
ref={(component) => { this.multiSelect = component }}
onSelectedItemsChange={this.onSelectedItemsChange}
selectedItems={selectedItems}
selectText="Pick Items"
searchInputPlaceholderText="Search Items..."
onChangeInput={ (text)=> console.log(text)}
altFontFamily="ProximaNova-Light"
tagRemoveIconColor="#CCC"
tagBorderColor="#CCC"
tagTextColor="#CCC"
selectedItemTextColor="#CCC"
selectedItemIconColor="#CCC"
itemTextColor="#000"
displayKey="name"
searchInputStyle={{ color: '#CCC' }}
submitButtonColor="#CCC"
submitButtonText="Submit"
/>
<View>
{this.multiSelect.getSelectedItemsExt(selectedItems)}
</View>
</View>
);
}
}The component takes 3 compulsory props - items, uniqueKey and onSelectedItemsChange. Other props are optional. The table below explains more.
| Prop | Required | Purpose |
|---|---|---|
| altFontFamily | No | (String) Font family for searchInputPlaceholderText |

| fixedHeight | No | (Boolean) Defaults to false.

-
Tokenized selected items can be displayed in any other part of the view by adding a
refto theMultiSelectcomponent like soref={(component) => { this.multiSelect = component }}. Then add this to any part of the screen you want the tokens to show up:this.multiSelect.getSelectedItemsExt(selectedItems). TheselectedItemsargument passed into the above mentioned method is the sameselectedItemspassed as the main component selected items prop. (See example above). -
If users shouldn't be able to select any of the items in the dropdown list, set a
disabledkey to true in the item. Such item will be rendered in gray and won't be clickable. -
When using the
singleprop,selectedItemsshould still be passed in as an array of selected items keys. Also, when an item is selected in the single mode, the selected item is returned as an array of string. -
The
itemsprops must be passed as an array of objects with a compulsorynamekey present in each object as the name key is used to display the items in the options component.
To use, add ref to MultiSelect component in parent component, then call method against reference. i.e.
<MultiSelect
ref={c => this._multiSelect = c}
...
/>
clearSelectedCategories = () => {
this._multiSelect.removeAllItems();
