將鼠標懸停在引導程序中的導航欄鏈接上的子菜單
[英]Sub menu on hover over navbar link in bootstrap
問題描述
我想在我的bootstrap項目中實現一項功能，例如每當有人將鼠標懸停在我的導航欄鏈接上時，它就會像下面的菜單一樣垂直顯示詳細菜單
我知道如何將鼠標懸停在導航欄鏈接上，但是如何在鼠標懸停時填充此類子菜單。 已經存在任何教程或示例，然后與我分享。 如果沒有，請分享想法！
謝謝！

這可能是一種選擇，您只需要調整邊距和填充即可。

試試這個，它應該適用於桌面視圖和移動視圖：
$(document).ready(function(){ $(".dropdown").hover( function () { if (!$($(this).parents()[3]).find('.navbar-toggle').is(":visible")) { $(this).find('.dropdown-toggle').trigger('click'); } }, function () { if (!$($(this).parents()[3]).find('.navbar-toggle').is(":visible")) { $(this).find('.dropdown-toggle').trigger('click'); } } ); });

單擊子菜單后，Bootstrap折疊的導航欄不會保持折疊狀態
[英]Bootstrap collapsed navbar not staying collapsed after clicking sub menu
當我 hover 在導航欄元素本身上時，我的子導航欄是可見的，但當我在它上面時，我的子導航欄消失了 hover
[英]my sub navigation bar is visible when i hover over the navbar element itself but disappears when i hover over it
