Currently, I can set something like opacheader for all libraries or specific libraries, but I cannot tell it what to display for no libraries. Without logging in on the OPAC, I see the header. I haven't identified a library. It is showing opadheader assigned to all libraries. If I have an opacheader for a specific library, and I log in as a patron to that library, both headers show. What I would want to see is a way to define an element for when you are not logged in, and then a specific header all libraries, and then if I want specific headers for certain libraries, they would take the place of the all libraries one. So, what we need is: - library location of None/Not selected - a check box or something to indicate we want it to override all other elements of the same name, rather than in addition to.
