Hi benB,
1) When I clicked on 'Store' next to 'Filed Under' – http://em.eidev.me/category/beech-mountain/store/
I get a page saying that no posts match that criteria.
The default for Categories and Tags that come with WordPress will only show normal blog posts. You can add some code to your theme/functions.php in your theme to remove this WordPress feature:
add_filter('pre_get_posts', 'show_all_types'); function show_all_types($q) { if (is_category() && is_archive()) { $q->set('post_type', 'any'); } }
2) It would be nice to be able to keep the same URL structure but somehow add 'store' such as the following:
http://em.eidev.me/attraction/beech-mountain-north-carolina/store/general-mercantile/
it is not possible with types.
