From what I've read, Wordpress 3.1 now supports hierarchical taxonomies when you register a taxonomy with:
rewrite => array('hierarchical' => true )
I am trying to achieve urls that appear as: http://www.domain.com/tax-name/parent-tax/child-tax, instead of http://www.domain.com/tax-name/child-tax
I was wondering if you had any plans to implement this into a future release? In the mean time, could you recommend a hack to achieve this?
