I don’t exactly understand what you are referring to as “nested” categories. Do you mean supporting the Google RDF for breadcrumbs? From what I just read, I can’t believe Google published that (in a bad way). While having a standardized format for containing breadcrumb trails is cool, their current RDF contains way too much redundant information. I will keep my eye on this (thanks for pointing it out), but I don’t want to implement it until it is a standard that actually makes sense.
By “nested” I mean parent-category and child-category (and grandchild-category).
Sorry for typos, it was just very late evening 🙂
It’s just an idea…
I’m going to preface this with the following: Breadcrumb NavXT has supported hierarchical categories for years now. And, it has also supported hierarchical custom taxonomies for about 10 months now. Now that I’ve said that, what I assume you mean by nested categories is that the tags that surround them are nested. An example would be the second example on the linked Google page.
I understand the line of thinking for this, it provides a sense of hierarchy through markup. However, it is sort of wasteful (mostly excessive tags), and can be a pain to style. I’ll be honest with you, you can’t do this with the standard display functions. I could create a bcn_display_nested() to do this task. Is that something you’d be interested in?
would be nice.
But somehow I don’t see difference between current styling and nested styling, live example: http://css.maxdesign.com.au/listamatic2/horizontal04.htm
In both cases there are opening tags and closing tags. And Yes it is little bit harder…
Difference: ?
<div class="navigation_breadcrumbs"><span class="parent">Parent</span> > <span class="child">child</span> > <span class="grandchild">grandchild</span></div>
and
<div class="navigation_breadcrumbs"><span class="parrent">Parent > <span class="child">child > <span class="grandchild">grandchild</span></span></span></div>
PS From all breadcrumb navigation here on wordpress.org, this is most preferred for my web, because of it’s customization possibility 🙂
For easy understanding about customization of nested navigation.
<div class="navigation_breadcrumbs"><span class="parent"><em class="parent_wrap">Parent</em> > <span class="child"><em class="child_wrap">child</em> > <span class="grandchild"><strong class="grandchild_wrap">grandchild</strong></span></span></span></div>
where <em> and <strong> can be added in option page.
As an update to this. Since I still do not have multi site support working in Breadcrumb NavXT, and need to concentrate on that for the next release, 3.7.0, this feature will not show up until the January release, 3.8.0.
As another update to this, it should be implemented in the SVN trunk now. For the sake of simplicity, most of the formatting for RDFa and Microformats is automatically applied, only a few things need to be set in anchors.
