        values={[ '--Choose--', 'one', 2, 3.5, { four: 4 }, [ 5, 6, 7 ], false ]} 
        selected={1} onChange={(data) => { console.log(data); }} />
    );
  }

Props

style

Right now you should always and only provide its height and width, otherwise the dropdown won't show up at all

values

An array of options. This should be provided with an array of strings. Any type other than string will be converted to its string representation

selected

An int indicating which option (zero-based) is currently selected

onChange(data)

Callback with data in the form data = { selected: 1, value: 'one' }
