[opencms-dev] hide advanced button in properties dialog

[Giuseppe Sorce]

Hi all,
I know, it's an old discussion... but I'll try to ask again.
I'm wondering if there is a way to prevent the advanced button to show up
when editing properties for a resource or at least a way to preventing the
update of these advanced properties (for users that are not admistrators or
projectmanagers).I remember it is a new feature provided by OpenCms 7.5.1. 
Isn't it?

Thank you in advance for your reply.Giuseppe SorceEngineering Ingegneria
