HTML-CSS菜單不工作子菜單

Question

我做了一個子菜單的菜單，當我懸停在Urunler導航它打開子項目，但當我盤旋到子項目他們丟失。所以我不能點擊/打開我想要的子項目。

HTML代碼，在這裏：

<div id="top_menu"> 
<ul id="menu_list"> 
    <li style="padding-right:50px;color:white">Telefon no: +90(312) 1234567</li> 
    <li class="selected"><a href="index.html">Ana Sayfa</a></li> 
    <li><a href="satisdakiler.html">Satıştakiler</a></li> 
    <li><a href="urunler.html">Ürünler</a> 
    <ul class="sub_item"> 
    <li><a href="#">Dekoratif Ürünler</a></li> 
    <li><a href="#">Hediyelik Ürünler</a></li> 
    <li><a href="#">Heykeller</a></li> 
    <li><a href="#">Promosyon Ürünleri</a></li> 
    <li><a href="#">Rolyef</a></li> 
    <li><a href="#">Işıklı Taşlar</a></li> 
    <li><a href="#">Maketler</a></li> 
    </ul> 

    </li><!--end of urunlers li--> 
    <li><a href="modelvekalip.html">Model ve Kalıp</a></li>

    <li><a href="iletisim.html">İletişim</a></li> 
    </ul> 
    </div> <!--End of top_menu -->
