Superfish：箭头或子菜单不显示

Question

根据我如何初始化Superfish，我得到箭头或子菜单显示在悬停，但不是两个。

箭头将显示：（但没有子菜单）

<script> 

jQuery(document).ready(function(){ 
    jQuery('#spice2011').superfish(); 
}); 

子菜单将显示：（但没有箭头）

<script> 

jQuery(document).ready(function(){ 
    jQuery('ul.spice2011').superfish(); 
}); 

这是CSS，它必须是罪魁祸首，但我看不到它。我所做的只是添加ul＃spice2011来定义导航宽度，但即使没有，也会得到与上述相同的结果。我已经设置了箭头的绝对图像路径：

/*** ESSENTIAL STYLES ***/ 
ul#spice2011 { 
width: 953px; 
} 

.sf-menu, .sf-menu * { 
margin: 0; 
padding: 0; 
list-style: none; 
} 
.sf-menu li { 
position: relative; 
} 
.sf-menu ul { 
position: absolute; 
display: none; 
top: 100%; 
left: 0; 
z-index: 99; 
} 
.sf-menu > li { 
float: left; 
} 
.sf-menu li:hover > ul, 
.sf-menu li.sfHover > ul { 
display: block; 
} 

.sf-menu a { 
display: block; 
position: relative; 
} 
.sf-menu ul ul { 
top: 0; 
left: 100%; 
} 


/*** DEMO SKIN ***/ 
.sf-menu { 
float: left; 
margin-bottom: 1em; 
} 
.sf-menu ul { 
box-shadow: 2px 2px 6px rgba(0,0,0,.2); 
min-width: 12em; /* allow long menu items to determine submenu width */ 
*width: 12em; /* no auto sub width for IE7, see white-space comment below */ 
} 
.sf-menu a { 
border-left: 1px solid #fff; 
border-top: 1px solid #dFeEFF; /* fallback colour must use full shorthand */ 
border-top: 1px solid rgba(255,255,255,.5); 
padding: .75em 1em; 
text-decoration:none; 
zoom: 1; /* IE7 */ 
} 
.sf-menu a { 
color: #13a; 
} 
.sf-menu li { 
background: #BDD2FF; 
white-space: nowrap; /* no need for Supersubs plugin */ 
*white-space: normal; /* ...unless you support IE7 (let it wrap) */ 
-webkit-transition: background .2s; 
transition: background .2s; 
} 
.sf-menu ul li { 
background: #AABDE6; 
} 
.sf-menu ul ul li { 
background: #9AAEDB; 
} 
.sf-menu li:hover, 
.sf-menu li.sfHover { 
background: #CFDEFF; 
/* only transition out, not in */ 
-webkit-transition: none; 
transition: none; 
} 

/*** arrows **/ 
.sf-menu a.sf-with-ul { 
padding-right: 2.25em; 
min-width: 1px; /* trigger IE7 hasLayout so spans position accurately */ 
} 
.sf-sub-indicator { 
position: absolute; 
display: block; 
right: .75em; 
top: .9em; 
width: 10px; 
height: 10px; 
text-indent: -999em; 
overflow: hidden; 
background: url(http://www.sea.edu/images/sea_images/arrows-ffffff.png) no-repeat 0 -100px; 
} 

li:hover > a .sf-sub-indicator, 
li.sfHover > a .sf-sub-indicator { 
background-position: -10px -100px; 
} 

/* point right for anchors in subs */ 
.sf-menu ul .sf-sub-indicator { 
background-position: 0 0; 
} 
.sf-menu ul li:hover > a .sf-sub-indicator, 
.sf-menu ul li.sfHover > a .sf-sub-indicator { 
background-position: -10px 0; 
} 

而这里是代码，菜单是使用表达式引擎2.4.0动态创建的。因为它会自动将列表项的内容包装在一个div中（我为第一个模仿，而不是动态创建），我是否需要对CSS做一些激烈的调整？

<nav>  
     <ul class="sf-menu" id="spice2011"> 
     <li> 
      <a href="{site_url}spice_2011">2011</a>

jQuery(document).ready(function(){ 
    jQuery('ul#spice2011').superfish(); 
});
