In the download package, the Angular demos have the same feature set that is shown in the Angular previews.
Most of the HTML version features are jquery based so those features can not be used in Angular. However, any CSS/HTML based features can be reused in Angular since the style.bundle.css includes all those static HTML features will be available in the Angular version.
