php - 显示每个类别最新帖子的下拉导航菜单

Question

所以我正在尝试在我的 WordPress 网站中处理导航菜单。我正在尝试从 hongkiat.com 复制导航菜单(如图所示)。

在 Hongkiat 的导航菜单中，您将看到五 (5) 个父类别(设计/开发、技术、灵感、社交商务和交易)。一旦用户将鼠标悬停在父类别上，它将显示父类别下的最新帖子。

无论如何，我设法对下拉菜单进行编码，其中显示父类别及其子类别。现在的困境在于如何在用户悬停的父类别下显示最新的帖子(至少 3 个帖子)。

无论如何，这是我的代码:

HTML/PHP

<ul>
    <?php 

        global $post;
        $myposts = get_posts('numberposts=3&offset=1');
        foreach($myposts as $post) ;


        $args = array(
        'show_option_all'    => '',
        'hide_empty'         => '0',
        'orderby'            => 'name',
        'order'              => 'ASC',
        'style'              => 'list',
        'use_desc_for_title' => 1,
        'child_of'           => 0,
        'hierarchical'       => 1,
        'title_li'           => (''),
        'show_option_none'   => __( '' ),
        'number'             => null,
        'echo'               => 1,
        'depth'              => 2,
        'current_category'   => 0,
        'pad_counts'         => 0,
        'taxonomy'           => 'category',
        'walker'             => null
        );
        wp_list_categories( $args ); 
    ?>
</ul>

CSS

.navone {

.navone ul ul ul {

.navone ul li ul li {
    padding:8px 10px;
    -webkit-transition: all .25s ease;

    -o-transition: all .25s ease;
    transition: all .25s ease;
}

.navtwo {
    display:inline;
}

如果有人可以帮助我或指出我缺少什么，因为我的代码不起作用。我的代码没有错误，但我没有实现我想要实现的目标。

有人可以伸出援助之手吗？
