Way to re-use field groups?

Hi,

With the Builder, you can assign a field group (meta box) to more settings pages to re-use the field group. Like this https://share.getcloudapp.com/6quv9bwO

Using code:

add_filter( 'rwmb_meta_boxes', 'your_prefix_function_name' );
function your_prefix_function_name( $meta_boxes ) {
    $meta_boxes[] = [
        'title'          => __( 'Field Settings page', 'your-text-domain' ),
        'id'             => 'field-settings-page',
        'settings_pages' => ['my-custom-settings', 'my-settings-2'],
        'fields'         => [
            ...
        ],
    ];
    return $meta_boxes;
}

Please read more on the documentation https://docs.metabox.io/extensions/mb-settings-page/#creating-settings-fields

Hi,

The field ID (meta key) is associated with the post/page ID or option name (setting page) so it's not possible to use the same field ID in other places on a page.

You can try to use the cloneable feature to duplicate a field or a group.
