Adding scrollbar to a Group in AX 2012 form

I need to set scrollbar in a Group as shown below since there are many more vertical fast tabs are available which are getting hide when opening any tab as you can see below . I have used tab and selected style as Fasttab. I have tried to set Scrollbar property of tab and its tabpages to yes but for no result…

Any help would be great!!!

Set the height property of tabpage to Column height
