subsubmenu1(青い背景)をsubmenu1(赤い背景)の下にスタックするにはどうすればよいですか?z-indexを使用してみましたが、機能しません。次のjsfiddleでは、subsubmenu1がsubmenu1の上にスタックされています。

position:absoluteで使用する必要がありますz-index

ホバーイベントでこのコードを試してください:

$(this).children("ul").animate({marginLeft:"50px"}).css({"position":"absolute", "z-index":"-1"});

トップナビゲーションで他の要素を非表示にするという点で

Replace this : $("#submenu1,#submenu2").children().hide();

With : $("#submenu1,#submenu2").children("ul").hide();スクリプトで。

幸運を !!
