I have my CPT, and I am trying to clone the group of Custom Fields in my metabox named as Credits.

I have these fields to be cloned each time, when the user hit on + Add Group button:

1. Text Field
2. TextArea Field

I have followed this link for reference -> Clone Group of Custom Fields

Now, I believe the code is right, but somehow, I can see only textfield is coming up. I have tried my best to get this working but failed. I need your help on this. Metabox Group extension is a paid extension, and I do not want make use of it

Code:

function gallery_credit_section( $meta_boxes ) {
    $prefix = 'prefix-';

    $meta_boxes[] = array(
        'id' => $prefix . 'gallery-credits',
        'title' => esc_html__( 'Credits', 'metabox-online-generator' ),
        'post_types' => 'gallery',
        'context' => 'advanced',
        'priority' => 'default',
        'autosave' => 'false',
        'fields' => array(
            array(
                'id' => $prefix . 'gallery-advisor',
                'type' => 'group',
                'clone' => true,
                'fields' => array(
                    array(
                        'id' => $prefix . 'gallery-advisor',
                        'type' => 'text',
                        'name' => esc_html__( 'Advisors', 'metabox-online-generator' ),
                        'placeholder' => esc_html('Author Name', 'metabox-online-generator')
                    ),
                    array(
                        'id' => $prefix . 'gallery-about-advisor',
                        'type' => 'textarea',
                        'name' => esc_html__('About Advisor', 'metabox-online-generator')
                    )
                )
            )
        )
    );

    return $meta_boxes;
}
add_filter( 'rwmb_meta_boxes', 'gallery_credit_section' );

Result:

As you can see, no name is there for the field, plus there is no textarea field too. Please help. Thanks 🙂
