Those cool tear-down menus in Office 97

Has anyone tried to imitate these using D3?  I'm suprised there is no
support for it since Borland went as far as the TCoolBar.

Even tear-down toolbar components would be pretty slick.  I remember
reading an ariticle in a Delphi mag about making rollup forms, but nothing
about teardown forms.  

If you know of anyone with examples of this out there, could you please let
me know?

Thanks!
