I have content type = CD. As there are many fields to describe each detail (artist, publisher, performers, band, producer etc.) i want somehow to give user option which field to pick. Of course this works by default, but i would like some kind of checkboxes in block for example when adding node, so user picks only 3 of 15 if he wants, and then
If CD is compilation or you have many artist (Opera for example), user will proly use all fields, if CD is one man band he will use far less.
I hope i gave good explanation of what i want to acchive.
