[wp-hackers] Dispay none for different categories

[Frank Bueltge]

Hello,

any one have a idea?
I will display none for a categories in edit post on admin-area.
I have not found a hook for the select and think, it is possible to display
none with css or javascript an load admin.
A this is not ao easy for a users with many categories in wordpress.

It is possible to hook an the meta box for categories and reduce the select
for categories ind the meta box on edit post?

Thanks for your ideas
Best regards
Frank
