 * Defines an AJAX command to open content in a dialog in a off-canvas dialog.
 * @ingroup ajax
 * @internal
class OpenOffCanvasDialogCommand extends OpenDialogCommand {

   * The dialog width to use if none is provided.

   * Constructs an OpenOffCanvasDialogCommand object.
   * The off-canvas dialog differs from the normal modal provided by
   * OpenDialogCommand in that a off-canvas has built in positioning and
   * behaviours. Drupal provides a built-in off-canvas dialog for this purpose,
   * so the selector is hard-coded in the call to the parent constructor.
   * @param string $title
   *   The title of the dialog.
   * @param string|array $content
   *   The content that will be placed in the dialog, either a render array
   *   or an HTML string.
   * @param array $dialog_options
   *   (optional) Settings to be passed to the dialog implementation. Any
   *   jQuery UI option can be used. See http://api.jqueryui.com/dialog.
   * @param array|null $settings
   *   (optional) Custom settings that will be passed to the Drupal behaviors
   *   on the content of the dialog. If left empty, the settings will be
   *   populated automatically from the current request.
