在移动设备中查看时，引导菜单完全显示。

Question

提前非常感谢！我是一名平面设计师，使用 SIMA 引导模板。我没有成功联系到模板的作者。除了当您在移动设备上查看网站时，所有内容都是犹太教，导航菜单会完全显示。用户必须手动单击导航选项卡才能隐藏菜单（可用性差）。我搜索了类似的问题，发现我有正确的元视图标签，我的导航类和 id 似乎都在那里。我的网站的链接是www.thesunkenweb.com/loteksystems 作者网站的链接（具有相同的结果）是https://readytheme.net/item/sima-one-page-multipage-template/ HTML 片段：
