OK I'll try to be more specific. I have a class employees that contain different attributes: employees(first_name, last_name, phone_extension, branch). An employee works in a specific branch like corporate Human resources, finance, reception, etc. I created a folder with all employees. I would like now to create another folder that will contain only the employees of the Human Resources branch.
I'd suggest to use the enhanced object relation (eor) attribute
http://ez.no/community/contribs/datatypes/enhanced_objectrelation for the branch attribute
Create a new content type "branch"
On employee, add the eor attribute and say to select only the objects of the class branch
Create a override the view full for the branch attribute and display the list of the reverse related objects (ie. the employees)
That's it.
You can add or delete as many branches as you want.
