 * `controllerAs` - an alternative to the controller-as syntax, matching the API of directive definitions. Requires the `controller` option to be provided as well
 * `resolve` - members that will be resolved and passed to the controller as locals; it is equivalent of the `resolve` property for AngularJS routes
+* `animation` - set to false to disable animations on new modal/backdrop. Does not toggle animations for modals/backdrops that are already displayed.
 * `backdrop` - controls presence of a backdrop. Allowed values: true (default), false (no backdrop), `'static'` - backdrop is present but modal window is not closed when clicking outside of the modal window.
 * `keyboard` - indicates whether the dialog should be closable by hitting the ESC key, defaults to true
