Window Resizing and the CustomUI Ribbon Appearance

[hatman]

I have a fairly complex ribbon tab for an application that looks quite good when viewed fullscreen on a 1024x768 display. But as soon as the window size gets smaller than that, all of the groups in the tab collapse to icons that must be clicked to display the controls. The default ribbon tabs do not behave this way, instead there is some logic that causes controls to resize themselves, or select controls to be placed in a flyout menu, until you get so small that the collapsed icon is displayed. In was researching a way to create this behavior in my CustomUI, and though I had a viable path with this page which talks about SizeDefinitions: https://msdn.microsoft.com/en-us/library/windows/desktop/dd316846(v=vs.85).aspx. Alas, it is NOT an article that is applicable to the MS Office CustomUI.

Has ANYONE attempted this, or know of any articles, or well any leads whatsoever?
