我正在为我的菜单使用 Superfish jQuery 插件。在 Chrome 和移动 Opera 模拟器中，它工作正常，但在 Internet Explorer 11 中，CSS 属性 list-style:none 仅适用于菜单的顶层而不适用于切换的子菜单，尽管在开发中工具查看它似乎适用于适当的元素。结果是: 使用此 CSS:

/*** ESSENTIAL STYLES ***/
.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 (for all except IE7) **/
.sf-arrows .sf-with-ul {
    padding-right: 2.5em;
    *padding-right: 1em; /* no CSS arrows for IE7 (lack pseudo-elements) */
}
/* styling for both css and generated arrows */
.sf-arrows .sf-with-ul:after {
    content: '';
    position: absolute;
    top: 50%;
    right: 1em;
    margin-top: -3px;
    height: 0;
    width: 0;
    /* order of following 3 rules important for fallbacks to work */
    border: 5px solid transparent;
    border-top-color: #dFeEFF; /* edit this to suit design (no rgba in IE8) */
    border-top-color: rgba(255,255,255,.5);
}
.sf-arrows > li > .sf-with-ul:focus:after,
.sf-arrows > li:hover > .sf-with-ul:after,
.sf-arrows > .sfHover > .sf-with-ul:after {
    border-top-color: white; /* IE8 fallback colour */
}
/* styling for right-facing arrows */
.sf-arrows ul .sf-with-ul:after {
    margin-top: -5px;
    margin-right: -3px;
    border-color: transparent;
    border-left-color: #dFeEFF; /* edit this to suit design (no rgba in IE8) */
    border-left-color: rgba(255,255,255,.5);
}
.sf-arrows ul li > .sf-with-ul:focus:after,
.sf-arrows ul li:hover > .sf-with-ul:after,
.sf-arrows ul .sfHover > .sf-with-ul:after {
    border-left-color: white;
}

(菜单 ul 具有 sf-menu 类)。更有趣的是，在同一页面的第二次或另一次访问时，它会正确显示。然而，在第一次加载 IE 实例时，它总是显示错误。

编辑:当我改为为每个 ul 设置列表样式规则时，它会按预期工作。

不知道这样会不会更好。复制自 jquery git
