  // If no category is selected or the category is empty or our special empty
  // category render a 'header' that will appear instead of the columns.
  if (empty($vars['category']) || empty($content) || $vars['category'] == 'root') {
    $vars['header'] = t('Content options are divided by category. Please select a category from the left to proceed.');
  }
  else {
    $titles = array_keys($content);
    natcasesort($titles);

    // This will default to 2 columns in the theme definition but could be
    // changed by a preprocess. Ensure there is at least one column.
    $columns = max(1, $vars['column_count']);
    $vars['columns'] = array_fill(1, $columns, '');
