Question

我的下拉divs的高度受外層div在CHROME中的高度限制。這個問題在IE，Mozilla或任何其他瀏覽器中都沒有了。

我不知道什麼可能導致此，也jsFiddle工作完全正常..

    min-width:50px; 
     font-weight:bold; 

     display:inline-block; 
    max-width:120px; 
} 

和jQuery功能：

$(function() { 

     $(".hakkimizda").hover(function() { 
      $(this).find(".popup").stop().fadeToggle("fast"); 

     }); 
    }); 

    $(function() { 
     $(".altmenuacici").hover(function() { 
      $(this).find(".altmenu").stop().fadeToggle("fast"); 
     }); 
    });

您在#headercontent中使用overflow:hidden。只需將其刪除，懸停時將出現下拉菜單。因爲您同時具有固定的高度和隱藏的溢出，那個父母的孩子不會出現在指定的高度之外。
