[Zope] plone, open folder in menu by default

[Olivier Wambacq]

hello,

I have different usergroups in my plone site,

for example:
if a user with group "partners" logs in, he gets a menu, with the standard
items, and then the folder "Partners Area", this is a folder with all the
items specific for users in this group, not visible for other users.

but in plone menu, by default, this folder is closed, is it possible to have
it open by default?

thanks,
Olivier
