导航菜单不会在悬停时保持下拉

Question

希望这里有人可以帮助我。我创建了一个下拉导航菜单，它工作得很好，除了一旦你将鼠标悬停在下拉项目上，任何超过列表第二个的项目，它都不会悬停在上面并且菜单再次关闭。这是 CSS：

 ******************************************************
 *Design the main ul
 ******************************************************
*/ 
 #ajonav ul {
 background-color: #a01013; 
 padding: 0 0px;
 list-style: none;/*To remove the bullets*/
 position: relative;
 display: inline-block;
 }

/*
 ************************************
 *Design the main ul li
 ************************************
*/
 #ajonav ul li {
 float: left;
 border-right: 1px solid #a01013;
 }
 #ajonav ul li:hover {
 background-color: #a01013;
 }
 #ajonav ul li:nth-child(5){border-right:none; }


#ajonav ul li:hover a {
  color: #efb009;
 }

 #ajonav ul li a {
  color: #E4E4E4; 
  text-decoration: none;
  padding: 10px 10px;
  display: block;
  font-family: sans-serif,serif;
 }


/*
 ************************************
 *(Dropdown) Design the sub ul li
 ************************************
*/
/*
 ******************************************************
 *Hide the submenu ul at start
 ******************************************************
*/ 
 #ajonav ul ul{visibility:hidden;display: none;}
/*
 ******************************************************
 *Show the submenu when li gets hover
 ******************************************************
*/ 
 #ajonav ul li:hover > ul {

visibility:visible;display: block;}
 #ajonav ul ul {
 position: absolute;
 background-color: #a01013;
 padding: 0px;  
 }

 #ajonav ul ul li {
  position: relative;
  float: none; 
  border-top: 1px solid #727272;
 }

 #ajonav ul ul li a {
  padding: 15px 20px;
  color: #fff;
 } 

 #ajonav ul ul li a:hover {
color: #ffffff;
  background-color: #a01013;
 }

如果有人可以帮助我；我会很感激的。

Thank you trolle, 

   I created a jsfiddle and it worked fine in there; don't get why it's not staying the same way in the actual website page.  Strange.

编码似乎工作正常，除非包含褪色背景；你可以在这里查看-http://metroanimalshelter.org/testredesigns2.html-请原谅那里页面上的混乱；在解决错误之前，我有很多占位符图像。
