need a combo box kind of feature in a tab sheet.


Not very old to vaadin so I need to have something like in attached image. Can someone tell which UI component is used in the circled (in red) section.

probably a combo box within a tab inside a tab sheet, is what I am looking at.

A quick response will be highly appreciated.



that component in the Tori forum is actually just a PopupButton add-on within a HorizontalLayout. The links to other forum areas are just added to the popup’s contents. Other components in that bar are just some buttons and labels. You can see the source code of the forum at
if you want to take a closer look.

As for putting any components into the tabsheet’s tab bar, it’s not currently supported and will require some client-side coding to do. Either by extending the tabsheet or writing a totally new component.
