More than pages and posts

Add the above to your theme's functions.php file to add an additional, custom, post type. In this instance we're creating a post-type called "kit-lists".

See the WordPress.org Dashicons section for more menu icons. Change "dashicons-admin-customizer" for the name of the icon you'd like to use.
