如何修复此导航菜单 - 它不会显示

Question

您可以在http://prodenvermovers.wpupkeep.org

上查看网页

将鼠标悬停在“服务”页面上后，它不会显示下拉菜单。下拉菜单是通过 wp_nav_menu 在 wordpress 中制作的。我有 5 个页面，其中一个是服务页面，下拉菜单有 3 个页面。我也在使用 wp_bootstrap_navwalker

我已经尝试了很多东西。首先，我更改了 wp_bootstrap_navwalker

中的一些数据

     $atts['href']          = 'http://prodenvermovers.wpupkeep.org/services/';
     $atts['data-hover']    = 'dropdown';

我从 boostrap responsive 中删除了 absolute class 并且它出现了但是像这样查看图片 --> http://prntscr.com/oh5lzk 正如您在这张图片上看到的那样，它通过下拉菜单推送了我的徽标和免费估价。
