function OpenOffCanvasDialogCommand::__construct

Constructs an OpenOffCanvasDialogCommand object.

The off-canvas dialog differs from the normal modal provided by OpenDialogCommand in that an off-canvas has built in positioning and behaviors. Drupal provides a built-in off-canvas dialog for this purpose, so the selector is hard-coded in the call to the parent constructor.

Parameters

string|\Stringable|null $title: The title of the dialog.

string|array $content: The content that will be placed in the dialog, either a render array or an HTML string.

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.

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.

string $position: (optional) The position to render the off-canvas dialog.
