php - Trying to order results of wp_query by the membership and sort order in wp_nav_menu -

my goal provide easy use interface non-technical site admins "drag , drop" order of slideshow on homepage of wordpress site.

i using wp_query build "featured slideshow" highlights other pages on homepage of site.

in order provide easy way web site admins manage order/appearance of these slides, wanted provide them custom wp_nav_menu item use "drag , drop" set order of slides on homepage.

i have since found out syntax 'orderby' in wp_query not referring wp_nav_menu order , has page_meta value sort order.

my question is, how can pass values wp_nav_menu wp_query can use orderby?

or

how can create "drag , drop" interface web admins manage order of slideshow without having go edit each pages sort order?

if 'featured' post type post or page, can specify orderby => menu_order within $args this.

.e.g

$args = array(     'post_type' => 'my-post-type',     'orderby' => 'menu_order' ); $query = new wp_query( $args );
