Where are "Paired buttons"?

Hi!

I am not sure I am calling the widget properly though, but e.g. iTunes demo has those “coupled” buttons to switch layout view from list to icons, or demo sampler has them right/top corner to go forward/backward etc.

Where I can find them??

Both of those cases use just buttons with custom css to make them go together. Buttons are just boxes, with no margins. First button has rounding on left side, last button has rounding on right side. The examples uses NativeButton as a base but I have myself used the standard Button for that.

There is a ready made add-on that themes the buttons for you:
ButtonGroup

:cold:

This one could be in the standard Vaadin.
