子菜单悬停显示限制(Submenu hover display restriction)

 我有个人项目的问题， http://mail.fixca.com.gt/ 。 在Drupal 8上使用配置文件头脑风暴 
 
 菜单不显示创建的子菜单。 我已经： 
 
 
 
 在菜单项上设置显示扩展模式。 
 
 
 设置块上的最大菜单级别显示。 
 
 
 试图创建一个新的菜单和CSS它让它显示子菜单 
 .submenu {display：none; } 
 .companymenuli：hover> ul {display：block; } 
 
 
 但它从不显示子菜单。 我意识到这可能是我做得不对的事情，但我找不到解决方案。 
 
 Drupals网站上的HTML显示如下 
 
 来自Chrome开发人员的HTML 
 
 我认为这可能是对主题本身的某种限制。 
 
 我非常感谢你的帮助。 如果你有什么提示，我可以在哪里找到解决方案。 
 
 谢谢。 

I have a problem with a personal project, http://mail.fixca.com.gt/. on Drupal 8 with the profile Brainstorm
 
The menu doesn't display the submenus created. I have already:
 
 
 
Set Show Expanded mode on the menu item.
 
 
Set the max menu level display on the block it self. 
 
 
Tried to create a new menu and CSS it to get it display the submenu
 
.submenu{ display:none; }
 
.companymenuli:hover > ul{ display:block; }
 
 
but it never shows the submenu. I realise that it might be something I'm just not doing right, but I cann't find the solution. 
 
The HTML on the Drupals Website shows like this 
 
HTML from chrome developer
 
I think that it might be some kind of restriction on the theme itself. 
 
I really appreciate your help. If you have give mi a hint on where I might be able to find the solution. 
 
Thank you.
