[Zope] Inner ZClasses

[Gilles Lenfant]

Hi,

I made a container ZClass (called "Main") inheriting from ZObjectManager
I made another ZClass (called "Sub")
"Main" objects may contain only "Sub" objects that have no sense when =
outside of a "Main" object.
But the "Add" drop box in the ZMI folder content panel shows "Sub" =
meta_type. And "Sub" objects in a folder have no sense.

How can I remove this "Sub" from the "Add" drop box ?

Thanks in advance.
