The sub-navigation will not be programmatically determined. The need here is to be able to configure each item in the breadcrumbs to be able to expose a hidden div the contents of which can/will be determined in a case-by-case basis.
Example Breadcrumb String:
Home > Enrollment > Course Offering > ENGL249
- For some items in the breadcrumbs, there are few "peer" pages (e.g. major modules of KS--enrollment, curriculum management, etc.), and showing a simple list of links to those pages will suffice. Again, it seems to me that these would be difficult to determine programmatically.
- For some items in the breadcrumbs there are many peer pages, too many to display in a simple list actually (e.g. courses, or people), and a lookup widget of some sort may be needed (simple lookup, autosuggest, or combo box).
