Drupal: fieldgroup_view_group to print multigroup in block

Question

I'm trying to use the fieldgroup_view_group function to print a multigroup inside a block.

The fieldgroup_view_group function looks like this:

<?php
function fieldgroup_view_group($group, &$node, $teaser = FALSE, $page = FALSE) {
  $group_name = $group['group_name'];
  $field_types = _content_field_types();

  // Clone the node to prevent from altering the original.
  $node_copy = drupal_clone($node);

  // Use 'full'/'teaser' if not specified otherwise.
  $node_copy->build_mode = isset($node_copy->build_mode) ? $node_copy->build_mode : NODE_BUILD_NORMAL;

  // Build the content element for individual fields in the field group.
  if (!isset($node_copy->content)) {
    $node_copy->content = array();
  }
  foreach (array_keys($group['fields']) as $field_name) {
    $field = content_fields($field_name, $node_copy->type);

    if (isset($node_copy->{$field_name})) {
      $items = $node_copy->{$field_name};

      // One-field equivalent to _content_field_invoke('sanitize').
      $module = $field_types[$field['type']]['module'];
      $function = $module .'_field';
      if (function_exists($function)) {
        $function('sanitize', $node_copy, $field, $items, $teaser, $page);
        $node_copy->{$field_name} = $items;
      }

      $field_view = content_field('view', $node_copy, $field, $items, $teaser, $page);
      // content_field('view') adds a wrapper to handle variables and 'excluded'
      // fields for node templates. We bypass it and get the actual field.
      $node_copy->content[$field_name] = $field_view[$field_name];
    }
  }

  // Build the content element of the field group itself.
  fieldgroup_build_content($group, $node_copy, $teaser, $page);

  // fieldgroup_build_content() adds a wrapper to handle variables and 'excluded'
  // groups for node templates. We bypass it and render the actual field group.
  $output = drupal_render($node_copy->content[$group_name]['group']);

  return $output;
}
?>

And example of the function being used is like this:

<?php
function content_multigroup_content_multigroup_content_type_render($subtype, $conf, $panel_args, $context) {
  if (!isset($context->data)) {
    return;
  }
  $node = drupal_clone($context->data);

  // Extract the node type and fieldgroup name from the subtype.
  list($node_type, $group_name) = explode(':', $subtype, 2);

  // Get a list of all fieldgroups for this node type.
  $groups = fieldgroup_groups($node_type);

  if (!isset($groups[$group_name])) {
    return;
  }
  $group = $groups[$group_name];

  // Render the field group.
  $node->build_mode = NODE_BUILD_NORMAL;
  $group['settings']['display']['label'] = $conf['label'] == 'normal' || !empty($conf['override_title']) ? 'hidden' : $conf['label'];
  $group['settings']['display']['full']['format'] = $conf['format'];
  $group['settings']['display']['full']['exclude'] = 0;
  $group['settings']['multigroup']['subgroup']['full']['format'] = $conf['subgroup'];
  $group['settings']['multigroup']['subgroup']['full']['exclude'] = 0;
  $output = fieldgroup_view_group($group, $node);

  $block = new stdClass();
  if ($conf['label'] == 'normal') {
    $block->title = t($group['label']);
  }
  $block->content = !empty($output) ? $output : $conf['empty'];
  return $block;
}
?>

Can somebody show me how to print one multigroup using this function? (And then I can hopefully figure out how to print the rest of my groups.)

Thanks.

You may want to check how this module does it: http://drupal.org/project/multistep

It allows you to create multistep CCK forms by putting fieldgroups in each step.
