Provide a structural label for top-level navigation, this will make
the relationship far more explicit. Using the labels from you main
navigation device as headings for the sub-menus will also serve to
strengthen the relationship.
True. And you've helped me fill in a gap:
One difference between nesting and linking lists is the way in which
parents & children are linked bidirectionally. Their relationship is
always clear in a nested list purely from the structural position of
the child inside the parent. To get from the child to the parent you
simply go up or outward one level.
With linked lists, the connection from parent to child is explicit
through the parent item's anchor to the child, and the headline of
each child menu can be hyperlinked back to the parent item.
So what I proposed as a singly-linked list easiliy becomes doubly-linked.
