Im looking for a way to add a custom meta box to a custom post type that will allow the user/client order the posts to show up how they want on the site. Is this possible? Basically using a very similar functionality to "page attributes"...
You can add
page-attributes support to the post type. This will cause a meta box to appear with an "order" field to do just what you want.
<?php add_post_type_support('your_custom_post_type', 'page-attributes');
Or you add
supports argument in register_post_type.
