react-native-selectbox

This is a platform independant (Android / iOS) version of the native picker / selectbox that react-native has. It's basically the Android version and the iOS version merged into one: only show a single selected label and only after clicking on this show the full list of items.

This is a derivation of the react-native-modal-picker by d-a-n I've simplified this a bit and removed alot of state handling preferring outside control. This allows for Redux state handling. I've also added the option of having the react-native-picker prompt feature. The prompt is a simple text above the list inside the modal.

Install

npm i react-native-selectbox --save

Usage

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 Selectbox from 'react-native-selectbox'

[..]

class App extends React.Component {

    ...

    _onChange = (item) => {
        // the full item as defined in the list of items is passed to the onChange handler to give full
        // flexibility on what to do... 
    }

    render() {
        const items = [
            { key: 0, label: 'Fruits', value:'some value' },
            { key: 1, label: 'Fruits', value:{this: "could", be:"anything"} },
        ];

        return (
            <View>
                <Selectbox
                    selectedItem=this.props.selectedItem
                    onChange={this._onChange}
                    items=items />
            </View>
        );
    }
