No scrollbar when using MainMenu or GroupBox

Abstract: MainMenu and GroupBox are qooxdoo controls. Any form with a qooxdoo control will not have a scroll bar.

Q. I have a form with with MainMenu or a GroupBox. I find the form will not scroll. Why?

A. The MainMenu and GroupBox controls are qooxdoo controls. That is a *feature* of qooxdoo. Qooxdoo controls are well suited to develop desktop interfaces, but are not nice to work with HTML-typed documents. MainMenu and GroupBox are qooxdoo controls, so when it initializes the engine, the browser doesn't scroll absolute divs on your document
