i have a custom taxonomy defined for "Projects" and a page that shows all the projects. In this page there's a jquery filtering menu (isotope). Initially the page must show all the projects but chronologically ('chronological' is a category and 1970, 1980, 1990, etc are subcats for a Projects element) ordered in DESC mode.
Now the query that initially shows the Projects in the page is
query_posts('post_type=portfolio&project-type='.get_post_meta($post->ID, 'portfolio_page_cats', true).'&posts_per_page=-1&orderby=menu_order&order=ASC');
There are a lot of questions about this argument, i know. Please, what is the best way to do that?
