Problem:
Trying to create a page that Lists only the parent posts that actually have Children, not all the parent posts.

Solution:
1. Add this code in your theme’s or child theme’s functions.php file:

function child_exists_func( $atts ){
    extract( shortcode_atts( array(
        'child_post_type_slug' => '',
    ), $atts ) );
    $child_posts = types_child_posts($child_post_type_slug);
    if ($child_posts) {
        return true;
    }
}
 
add_shortcode( 'child-exists', 'child_exists_func' );

2. Register the ‘child-exists’ shortcode first in Toolset >> Settings >> Front-end Content >> Third-party shortcode arguments.

3. Then add this shortcode in your View >> Loop Output Editor:

 [wpv-conditional if="( '[child-exists child_post_type_slug=belong]' eq '1' )"]
[wpv-post-link]
[/wpv-conditional] 

==> Where as “belong” is your child post type slug that you should replace.
