各位前輩早安~

事情是這樣的

我想要改的像範例
https://getbootstrap.com/docs/4.1/examples/starter-template/#
的下拉，
https://ithelp.ithome.com.tw/upload/images/20240106/20119035suSvizikHM.png

但是我的導覽頁跟內文分開
https://ithelp.ithome.com.tw/upload/images/20240106/20119035i9t6x4RJnW.png

但是怎麼改都無法長的一樣，依序展開下拉選單樣子

這是未改前的樣子

我是導覽頁跟內文分開
所以是按導覽頁下方就可以顯示相對的內頁
這裡也是我模仿範例卡關的地方
因為範例沒有內頁顯示

導覽頁程式碼

煩請各位大大提點

感激不盡~

最佳解答

看起來 你的code沒有跟原版貼近 效果出不來是正常的
原版用的是 ul li
放一段我的原碼給你參考 我的bootstrap版本高一點是5.1 你的版本是4.1 不過差異不大
我這段 做出來的效果是 logo + 兩組下拉(如圖)

但我的core版本與你不同 你就要想辦法處理了
