            'fontawesome' => isset($css[$js_outlink]['fontawesome']) ? $css[$js_outlink]['fontawesome'] : 'font-awesome.min',
            'main'        => 'main.min',
            'select' => 'select-tree',
        ));

在790行插入如下代码

wp_enqueue_script('select',  ZIB_TEMPLATE_DIRECTORY_URI . '/js/libs/select-tree.js', array('jquery'), THEME_VERSION, true);

在文件 wp-content/themes/zibll/pages/newposts.php 中，194 – 213 行代码替换如下：

<select class="form-control" id="category" name="category" tabindex="5">
                                <?php
                                $cat_ids = _pz('post_article_cat', array());

                                $cats = get_categories(array(
                                    'orderby'    => 'include',
                                    'include'    => $cat_ids,
                                    'hide_empty' => false,
                                ));

                                if ($cats) {
                                    foreach ($cats as $cat) {
                                        echo '<option value="' . $cat->term_id . '" ' . selected($cat->term_id, $in['cat_id'], false) . ' data-pid="'.$cat->parent.'">' . $cat->name . '</option>';
                                    }
                                } else {
                                    echo '<option value="1" selected="selected">' . get_category(1)->name . '</option>';
                                }

                                ?>
                            </select>

在此文件末尾增加

?>
<script>
    $("#category").selectTree();
</script>
