Groups Functionality

Is there a way to get the functionality of MB Groups without purchasing the plugin? $29 is a little steep especially when the others are $19.

I have added the following code but only this is showing up...

<?php
// Register settings page. In this case, it's a theme options page
add_filter( 'mb_settings_pages', 'prefix_options_page' );
function prefix_options_page( $settings_pages )
{
	$settings_pages[] = array(
		'id'          => 'options',
		'option_name' => 'options',
		'menu_title'  => __( 'Options', 'textdomain' ),
		'icon_url'    => 'dashicons-edit',
		'style'       => 'boxes',
		'columns'     => 1,
		'tabs'        => array(
			'general' => __( 'General Settings', 'textdomain' ),
		),
		'position'    => 2,
	);

	$settings_pages[] = array(
		'id'          => 'work',
		'option_name' => 'work',
		'menu_title'  => __( 'Work', 'textdomain' ),
		'icon_url'    => 'dashicons-admin-customizer',
		'style'       => 'boxes',
		'columns'     => 1,
		'position'    => 2,
	);
	return $settings_pages;
}

// Register meta boxes and fields for settings page
add_filter( 'rwmb_meta_boxes', 'prefix_options_meta_boxes' );
function prefix_options_meta_boxes( $meta_boxes )
{
	$meta_boxes[] = array(
		'id'             => 'general',
		'title'          => __( 'General', 'textdomain' ),
		'settings_pages' => 'options',
		'tab'            => 'general',
		'fields' => array(
			array(
				'name' => __( 'Logo Dark', 'textdomain' ),
				'id'   => 'logo_dark',
				'type' => 'file_input',
			),
			array(
				'name' => __( 'Logo Light', 'textdomain' ),
				'id'   => 'logo_dark',
				'type' => 'file_input',
			),
			array(
				'name' => __( 'Hello Bar', 'textdomain' ),
				'id'   => 'hello_bar',
				'type' => 'wysiwyg',
			),

		),
	);

	$meta_boxes[] = array(
		'id'             => 'project',
		'title'  => __( 'Featured Work' ),
		'tab'            => 'featured',
		'settings_pages' => 'work',
		'fields' => array(
			array(
				'id'     => 'work-featured-upload',
				// Group field
				'type'   => 'group',
				// Clone whole group?
				'clone'  => true,
				// Drag and drop clones to reorder them?
				'sort_clone' => true,
				// Sub-fields
				'fields' => array(
					array(
						'id'               => 'plupload_image',
						'name'             => __( 'Plupload Image (Alias of Image Upload)', 'your-prefix' ),
						'type'             => 'plupload_image',
						// Delete image from Media Library when remove it from post meta?
						// Note: it might affect other posts if you use same imagefor multiple posts
						'force_delete'     => false,
						// Maximum image uploads
						'max_file_uploads' => 2,
					),
				),
			),
		),
	);
	return $meta_boxes;
