Vaadin app inside another Vaadin App using browser frame

am new to vaadin.

Vaadin Version of both apps - 7.4.1

Am trying to fit one vaadin app inside another vaadin app using browser frame.

Am facing a problem like …the vaadin app inside the browser frame is not completely displayed … it displays in a small window without scroller.

Tried below but no luck.


Any way to implement the full vaadin page inside the browser frame with a scroller?.
