See docs for ng-for https://angular.io/docs/js/latest/api/directives/NgFor-class.html. Notice that the annotation from https://angular.io/docs/js/latest/api/directives/NgFor-class.html are not showing up.

There should be a separate section (above Members) called Annotations which should show:

@Directive({
  selector: '[ng-for][ng-for-of]', 
  properties: ['ngForOf'], 
  lifecycle: [LifecycleEvent.onCheck]
})
