My question is pretty basic. How to add styling from a css-file to a basic vaadin component? What I do NOT want to use: PolymerTemplate getStlye().set(...)

VaadinSession session = VaadinSession.getCurrent() ; // Fetch current instance of `VaadinSession` to use its key-value collection of attributes. session

I know Vaadin 10 (Vaadin Flow) is a major re-write of Vaadin, is the widget changed in name or not yet available? Possibly in Vaadin 14 Update: A MenuBar widget is planned for development by Vaadin Ltd, scheduled for Vaadin 14 release. See the manual . On GitHub, see Issue # 4694 MenuBar component .
