Something like Panel in vaadin

Exist any possibility to create similar panel like panel from attached jpg ?

Exist this component or must I modify css for normal Panel ?

You can achieve that effect with almost anything from a CSS Layout to a custom widget:
(and can be achieved also with a
GWT CaptionPanel
, as a comment in the link suggests).

I’m not aware of there being a component that looks just like that in the standard component set, but it’s not hard to create.
