I have a system where we have a hierarchical structure of items (x nr of child items) where data from the parent is displayed as a "header" and the child items (and data associated with them) are displayed in a table below. When selecting a child item the pattern is repeated, so it moves up as the parent (with a breadcrumb added to access the first parent) and its child nodes in a table below.
For each item there is associated detail information that will look basically the same for each item. It will be quite a lot of information, so it might require quite some space. The question is how to solve the pattern for this? Is there a clever way to access the details? Should it be a new page and it that case how should you navigate between the pages? Should it be a big modal window? Other ideas?
Thankful for any input
