[Closed] Post Relationship Parent Only in Drop Down

I've created a hierarchical post type called "Groups" that obviously will have parent and children pages. "Groups" has a post relationship with another post type "People". When I go to create a new People post is there a way to only show the parent items from my "Groups" post type in the drop down?

Hi brianG-4,

It is not possible within current version of Types, and I put it into our to-do list as a feature request. our developers will take care of it.

Thanks! Typically, what's the time-frame for new features to get added? Are we talking weeks? months?

Sorry, I am not sure when will it be applied into Types plugin, if you need, there is a workarround:
1) modify the Types plugin file \wp-content\plugins\wp-types\embedded\includes\post-relationship.php, line 290
From:

        'suppress_filters' => 0,

To:

        'suppress_filters' => 0,
		'post_parent' => apply_filters( 'wpcf_pr_belongs_post_parent', null,  $type, $post),

2) add codes in your theme/functions.php:

add_filter( 'wpcf_pr_belongs_post_parent', 'parent_items_func', 10, 3 );
function parent_items_func($post_parent, $post_type, $post){
	if(is_admin() && $post_type == 'groups' && get_post_type($post->ID)=='people'){
		$post_parent = 0;
	}
	return $post_parent;
}

Please replace "groups" with the slug of post type "Groups", and replace "people" with the slug of post type "People"
