即使隱藏在移動菜單中，下拉列表也會出現（懸停時）

[英]Dropdown list appears (on hover) even when it's hidden inside the mobile menu

問題描述

在我的導航欄中，我有一個 li 項目，當有人將鼠標懸停在它上面時會打開一個下拉菜單。 在小屏幕中，我有一個隱藏它的漢堡菜單。

問題在於，在移動視圖中，即使 li 項目在菜單中“隱藏”時，當有人將鼠標懸停在其在屏幕上的位置上時，它也會出現（即使它隱藏在菜單中）。

我認為這可能是因為我設置了“可見性：隱藏；” 但我不知道該怎么做。

我的意思是當有人將它懸停在桌面視圖上時我想下拉，但在移動設備上我只想在有人打開菜單然后將鼠標懸停在它上面（或者單擊它）時才下拉。

為了節省空間，我只在下面包含了我認為更相關的代碼。 

 $(function() { $(".toggle").on("click", function() { if ($(".item").hasClass("active")) { $(".item").removeClass("active"); } else { $(".item").addClass("active"); } }); });
