好的，我已經週期性地查看了這個約6周的時間，到目前爲止一直無法弄清楚如何解決這個問題。儘管我認爲這對於擁有更多經驗的人來說是一件小而相對簡單的事情。下拉菜單問題，DIV和/或CSS問題
背景： 我開始的模板有一個我喜歡的js幻燈片，並開始定製它。當我達到某個點時，我意識到我想添加一個下拉菜單。當我第一次添加ul下拉菜單時，似乎沒有任何事情發生。經過一段時間的調整後，我創建了一個測試頁面，我只添加了下拉菜單，查看js是否以任何方式影響它，並且按預期工作。然後，我只添加了js，看看我對js的知識是否影響它並且工作（沒有對齊信息）。
在這一點上，我回到原來的代碼，它停止工作。所以我上網了，並得到了一些示例代碼，以便我知道該如何工作，但也無法正常工作。有一次，我開始搞亂HTML中的div標籤，並且能夠獲得我所尋找的內容的某些相似之處，儘管內容有時在翻滾時開始下移;其他時候它會在100％的時間內丟棄內容。我開始和z-index一起玩，無論我做了什麼，似乎也沒有什麼不同。
問題： 我在這裏看不到什麼？我要找的所有內容都是一個下拉菜單，它可以覆蓋js幻燈片的頂部而不會將其推下。我很確定這個問題是圍繞這樣一個事實進行的，即有很多div來做這個佈局，並且它們以某種方式衝突。任何人可以幫助的幫助將是絕對驚人的，因爲我瘋了。

你的問題不是太寬泛，太具體:-)你應該嘗試使它更短，更通用。也許刪除不需要的絨毛？ –
