Humm, ... in fact some code in fvwm was already there for this.
Apply the attached patch to the current cvs (really current)
or to the next snapshot and use the following config:
Colorset 5 Transparent, Tint black 50
MenuStyle * MenuColorset 5, PopupOffset 0 100, AnimationOff
and you get what you want :o)
However, I do not think that such patch will be applied before
fvwm-2.6.
