[Resolved] Can I Assign an Element to Every Page with a Certain Parent?

Hi,

We’ll have to use the generate_hook_element_display filter for this.

add_filter('generate_header_element_display' , function( $display, $element_id ){
    if( $element_id === 18769 && is_page() && $post->post_parent == 18053 ){
        $display = true;
    }
    return $display;
});

Just replace 18769 with your Header element ID and 18053 with your parent page’s page ID.
