To begin I am sorry for my english, but I am french.
It is possible to hide fields following the group ?
For example : I create a group ABC. When a user of his group create an Issue I don't want that the field 'Component' displays however, if it is a member of Developers group, I want that this field is available.
Which version I need if I want that groups and users are independant for every project ?
How can I do this ? Maybe it is only possible with an other version, but which version ? Professionnal ? Enterprise ?
