I wonder if content type of Arachetype can have dynamic attributes, that is, some attributes(including property in meta type, like "allowed_content_types" ) are displayed dynamically according to other specific attributes. Thanks in advance.
Most of the configuration is associated between Python content class and Plone using the FTI in portal_types. A dynamic portal_type or meta_type does not make much sense. Inherited attributes and methods can be overwritten of course within the implementation of your content class. For folder restrictions see
Thanks! This helps a lot.
