 */
class SwitchField extends CompositeField {

  public function __construct($checkboxField, $leftOption, $rightOption) {

    $this->checkboxField = $checkboxField;
    $this->leftOption = $leftOption;
    $this->rightOption = $rightOption;

    if(!$this->checkboxField instanceof CheckboxField){
      throw new Exception('First parameter of SwitchField must be an instance of CheckboxField');
    }

    parent::__construct(array($checkboxField, $leftOption, $rightOption));
  }

}

Example usage

$checkbox = new CheckboxField("Test", "Test", true);

  $fields->addFieldToTab(
    'Root.Test',
    new SwitchField(
      $checkbox,
      new LiteralField("TestLeft","TestLeft"),
      new LiteralField("TestRight","TestRight")
    )
  );
