    super(props)
    this.state = {
      defaultValue: 'Select a color',
      currentValues: []
    }
  }

  _handleChange(value) {
    this.setState({
      currentValues: getToggledValues(this.state.currentValues, value)
    })
  }

  render() {
    const { defaultValue, currentValues } = this.state
    return (
      <Select
        multiple
        onChange={value => this._handleChange(value)}
      >
        <Trigger>
          { currentValues.length > 0
            ? currentValues.join(', ')
            : defaultValue
          }
        </Trigger>
        <OptionList tag="ul" className="react-select-menu">
          <Option value="red">Red</Option>
          <Option value="green">Green</Option>
          <Option value="blue">Blue</Option>
        </OptionList>
      </Select>
    )
  }
}

Select Props

children: PropTypes.node.isRequired (Accepts 2 children)

The first child is used as the trigger and the second child is used as the options that will be displayed upon clicking the trigger.

multiple: PropTypes.bool

When true this allows multiple options to be selected.

disabled: PropTypes.bool

Puts the select menu in a disabled state.

autoWidth: PropTypes.bool

Determines if the options should be the same width as the trigger.

onChange: PropTypes.func

Callback when an option has been selected. Passes back the value that was selected.

React ARIA Components

Trigger, OptionList, and Option are exported directly from React ARIA

Utilities

buildOptionsLookup: (array options)

  ]},
  { label: 'Cats', optgroup: [
    { value: 'munchkin', label: 'Munchkin' },
    { value: 'persian', label: 'Persian' }

  'persian':  { value: 'persian', label: 'Persian' }
