jquery - Superfish:箭头或子菜单未显示

Question

根据我初始化 Superfish 的方式，我会在悬停时看到箭头或子菜单，但不会同时出现。

箭头将显示为:(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，它一定是罪魁祸首，但我看不到它。我真正做的就是添加 ul#spice2011 来定义导航宽度，但即使没有它，结果也与上述相同。我为箭头设置了绝对图像路径:

/*** 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;
}

这是代码，菜单是使用表达式引擎 2.4.0 动态创建的。因为它自动将列表项的内容包装在一个 div 中(我在第一个 li ul 中模仿了它，它不是动态创建的)，我是否需要对 CSS 做一些极端的事情来适应？
