generate_hook_element_display

The generate_hook_element_display allows us to bypass the Display Rules, so we can enable or disable an Element under our own conditions.

For example, if we want to assign a specific hook to Author Tom only:

add_filter( 'generate_hook_element_display', function( $display, $element_id ) {
    if ( 10 === $element_id && is_author( 'Tom' ) ) {
        $display = true;
    }

    return $display;
}, 10, 2 );

Another useful example is to set the hook to display on the parent page and all the child pages automatically:

add_filter( 'generate_hook_element_display', function( $display, $element_id ) {
    global $post;

    if ( 1180 === $element_id && ( is_page() && $post->post_parent == '415' ) ) {
        $display = true;
    }

    return $display;
}, 10, 2 );

You need to replace 1180 with the ID of your Element, and 415 with the ID of the parent page.
