Hiding the contrl groups of a RichTextItem

Hi,

I am using the RichTextItem with some predefined control groups. I am trying to find a way to hide the control groups when the form item is read only or disabled, but to no avail. Am I missing something?

If it is not already implemented, it would be very useful to have a function that allowed showing/hiding the control groups programatically.

Regards,

Martin
