要首先创建菜单，请随意使用快捷代码[AVIA_tree_menu root="your_root_document_title"] 通过将此添加到functions.php:

function sc_AVIA_tree_menu($atts) {
    extract(shortcode_atts(array(\'root\' => \'Start\',), $atts));  //default if empty.
    $page = get_page_by_title($root);

    $args = array(
        \'child_of\' => $page->ID,
        \'date_format\' => get_option(\'date_format\'),
        \'depth\' => 0,
        \'echo\' => 0,
        \'post_type\' => \'page\',
        \'post_status\' => \'publish\',
        \'sort_column\' => \'menu_order, post_title\',
        \'title_li\' => __($root)
    );
    echo \'<ul>\' . wp_list_pages($args) . \'</ul>\';
}
add_shortcode(\'AVIA_tree_menu\', \'sc_AVIA_tree_menu\');

设置没有子级的链接样式，使其看起来不可单击：

.pagenav ul li > a {
    text-decoration:underline;
    cursor:pointer;
}

.pagenav ul li.page_item_has_children > a {
    text-decoration:none;
    cursor: default;
}

此后，通过添加此项来防止单击，例如document.ready 在里面your_theme/js/functions.js:

$(\'.pagenav li.page_item_has_children > a\').click(function () {return false;});

我会接受另一个同样好或更好的答案。周末快乐！
