There are many snippets of code and various plugins that will generate various types of WordPress page (wp_list_pages) navigation but none achieve the specific navigation that my site requires.
I'm after a the kind of nav that is found on PHP.net.
See the nav in the left-hand sidebar on this page:
Here's what it provides:
1. A "vertical" breadcrumb or ancestral path back to the root.
2. A list containing the current page and it's siblings.
This kind of navigation allows us to move through deep and complex hierarchy relatively easily whilst still maintaining a good idea of where we are within the structure.
When viewing the parent page of the page I link above you'll see that the navigation pattern is preserved:
We can navigate to the children of the page using the list in the main content region.
So the complete navigation system is:
1. Sidebar nav incorporating a vertical breadcrumb and sibling navigation
2. Content nav listing just the children of the current page (but not all descendants).
My question is -- can this be done in WordPress and how?
Many thanks in advance.
