Code
function _book_parent_select($book_link) { if (variable_get('menu_override_parent_selector', FALSE)) { return array(); } // Offer a message or a drop-down to choose a different parent page. $form = array( '#type' => 'hidden', '#value' => -1, '#prefix' => '<div id="edit-book-plid-wrapper">', '#suffix' => '</div>', ); if ($book_link['nid'] === $book_link['bid']) { // This is a book - at the top level. if ($book_link['original_bid'] === $book_link['bid']) { $form['#prefix'] .= '<em>' . t('This is the top-level page in this book.') .

The maximum depth for a book and all child pages is !maxdepth. Some pages in the selected book may not be available as parents if selecting them would exceed this limit.', array('!maxdepth' => MENU_MAX_DEPTH)), '#options' => book_toc($book_link['bid'], $book_link['parent_depth_limit'], array($book_link['mlid'])), '#attributes' => array('class' => array('book-title-select')), '#prefix' => '<div id="edit-book-plid-wrapper">', '#suffix' => '</div>', ); } return $form; }
