Getting Started

By design, React Mobile Picker is a Controlled Component, which means the selected value of the rendered element will always reflect the valueGroups. Every time you want to change the selected item, just modify valueGroups values.
Here is an example of how to integrate React Mobile Picker:
import React, {Component} from 'react';
import Picker from 'react-mobile-picker-scroll';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      valueGroups: {
        title: 'Mr.',
        firstName: 'Micheal',
        secondName: 'Jordan'
      }, 
      optionGroups: {
        title: ['Mr.', 'Mrs.', 'Ms.', 'Dr.'],
        firstName: ['John', 'Micheal', 'Elizabeth'],
        secondName: ['Lennon', 'Jackson', 'Jordan', 'Legend', 'Taylor']
      }
    };
  }

  // Update the value in response to user picking event
  handleChange = (name, value) => {
    this.setState(({valueGroups}) => ({
      valueGroups: {
        ...valueGroups,
        [name]: value
      }
    }));
  };

  render() {
    const {optionGroups, valueGroups} = this.state;

    return (
      <Picker
        optionGroups={optionGroups}
        valueGroups={valueGroups}
        onChange={this.handleChange} />
    );
  }
}
