A couple of days ago I found myself with the issue of getting the top parent of any page (that one which doesn’t have any father), so after look in Wordpress documentation I found a nice function called get_page_hierarchy() and also no documentation about it.

Well one of the reason for the early launch of this blog is what you are looking for right now, the plugin that displays your categories without that anoying submit button, so it’s more that fair that this plugin be the first post in this blog.
