我刚刚在一个新网站上的后端工作，当我注意到前端出现大错误时，我卡住了试图解决这个问题。当你在iPhone上打开它时，下拉菜单会自动关闭（Bootstrap v3.3.1）
我有一个旧版本的网站，我一直在努力，并在新版本中移动并整理了其余部分。但是，当我转到iPhone上的Safari浏览器时，尽管在旧网站上复制了网站页眉和页脚（包含相同的菜单），但它并未正确加载下拉菜单。
当你按下菜单时，它将打开，然后立即在iPhone上关闭。但铬和Firefox浏览器工作正常。我试着去看论坛并更改bootstrap代码，但似乎没有任何工作。它只在响应菜单下拉菜单中执行。
奇怪的是，旧网站有全宽下拉菜单，新网站粘在右侧（不是全宽），就好像它没有正确加载一样。
