add_filter('piklist_post_types', 'adaptive_post_type');
 function adaptive_post_type($post_types)
 {
  $post_types['e2s_adaptive'] = array(
    'labels' => piklist('post_type_labels', 'Adaptive Resource'),
    'title' => __('Enter Custom Title'),
    'public' => true,
    'capability_type' => 'post',
    'rewrite' => array(
					'slug' => 'e2s_adaptive'

return $post_types;
}
