Hi,
Is it possible to disallow certain Edit Part to be drop to a Container? If
yes, could you please tell me how to achieve that?
e.g. I would like to change the Circuit to allow user to drop a AND gate
figure, but NOT a OR gate figure. It will show a Stop sign icon when I
select a OR GATE figure and move it over to Circuit and when I move the
cursor to a other container (e.g. Flow Container), it should a Drop icon and
I can add the OR gate to the Flow Container?
Thanks

Yes, your layout editpolicy would override either getTarget(Request), if you
want that container to not be targeted, or getCommand(Request), if you want
the container to be targeted, but you want to return an UnexecutableCommand
to get the NOT sign..
