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-selector-searchable'

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`) }} />

                // 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}
  />
);
