Usage
You can either use this component in its default mode, as a wrapper around your existing component or provide a custom component (where you need to control opening of the modal yourself). In default mode a customizable button is rendered.
See SampleApp
for an example how to use this component.
import ModalSelector from 'react-native-modal-multi-selector'
class SampleApp extends Component {
constructor(props) {
super(props);
this.state = {
textInputValue: ''
}
}
render() {
let index = 0;
const data = [
{ key: index++, section: true, label: 'Fruits' },
{ key: index++, label: 'Red Apples' },
{ key: index++, label: 'Cherries' },
{ key: index++, label: 'Cranberries', accessibilityLabel: 'Tap here for cranberries' },
// etc...
// Can also add additional custom keys which are passed to the onChange callback
{ key: index++, label: 'Vegetable', customKey: 'Not a fruit' }
];
return (
<View style={{flex:1, justifyContent:'space-around', padding:50}}>
// Default mode
<ModalSelector
data={data}
initValue="Select something yummy!"
onChange={(option)=>{ alert(`${option.label} (${option.key}) nom nom nom`) }} />
// Multi mode
<ModalSelector
data={data}
selectStyle={{borderColor: "black"}}
selectTextStyle={{color: "blue"}}
multi={true}
onChange={item => { console.log(item) }}
/>
// Wrapper
<ModalSelector
data={data}
initValue="Select something yummy!"
supportedOrientations={['landscape']}
accessible={true}
scrollViewAccessibilityLabel={'Scrollable options'}
cancelButtonAccessibilityLabel={'Cancel Button'}
onChange={(option)=>{ this.setState({textInputValue:option.label})}}>
<TextInput
style={{borderWidth:1, borderColor:'#ccc', padding:10, height:30}}
editable={false}
placeholder="Select something yummy!"
value={this.state.textInputValue} />
</ModalSelector>
// Custom component
<ModalSelector
data={data}
ref={selector => { this.selector = selector; }}
customSelector={<Switch onValueChange={() => this.selector.open()} />}
/>
</View>
);
}
}
Data Format
The selector accepts a specific format of data:
[{ key: 5, label: 'Red Apples' }]
Optionally provide a component
key which overrides the default label text. Optionally provide a unique testID
for each item:
[{
key: 5,
label: 'Red Apples',
// The next keys are optional --
component: <View style={{backgroundColor: 'red'}}><Text style={{color: 'white'}}>Red Apples custom component ☺</Text></View>,
testID: '5-red-apples'
}]
If your data has a specific format, you can define extractors of data, example:
this.setState({data: [{ id: 5, name: 'Red Apples' }]});
return (
<ModalSelector
data={this.state.data}
keyExtractor= {item => item.id}
labelExtractor= {item => item.name}
/>
);
