You can either use this component as an wrapper around your existing component or use it in its default mode. 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'

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} />
