Question

我是HTML列表的新手，我正在尝试禁用＆＃34;悬停弹出效果＆＃34;并列出主项下方垂直下方的所有子项，它们应保持可见状态，请帮助我了解这个特殊CSS中哪些属性会禁用此效果

CSS

#prod_nav {
    position: relative;
    z-index: 300;
    border-left: 1px solid #d7d7d7;
    border-right: 1px solid #d7d7d7;
    border-bottom: 2px solid #d7d7d7;
}

#prod_nav li.top {
    display: block;
    float: left;
    width: 170px;
    border-top: 1px solid #d7d7d7;
    border-bottom: 1px solid #fbfbfb;
    height: 31px;
}

#prod_nav li a.top_link {
    font-size: 11px;
    display: block;
    width: 159px;
    padding-left: 11px;
    line-height: 31px;
    color: #252525;
    text-decoration: none;
    font-weight: bold;
    cursor:pointer;
    background: #f0f0f0;
}

#prod_nav li a.top_link span, #prod_nav li a.top_link span.down {
    display: block;
    padding-right: 20px;
    background: url(../images/productmenu-arrow.gif) no-repeat right center;
}

#prod_nav li:hover a.top_link {
    color:#0072bc;
    background: #fff;
}

#prod_nav li:hover a.top_link span, #prod_nav li:hover a.top_link span.down { background: url(../images/productmenu-arrow-hover.gif) no-repeat right center; }

/* Default list styling */

#prod_nav li:hover {
    position:relative;
    z-index:200;
}

#prod_nav li:hover ul.sub {
    left: 170px;
    top: -1px;
    background: #fff url(../images/productmenu-leftborder.gif) no-repeat left top;
    border: 1px solid #e2e2e2;
    border-left: 0;
    white-space: nowrap;
    width: 384px;
    height: auto;
    z-index: 300;
}

#prod_nav li:hover ul.sub li {
    display: block;
    position: relative;
    float: left;
    width: 364px;
    font-weight: normal;
    background: url(../images/productmenu-section-bg.png) no-repeat right bottom;
    padding: 10px 0 10px 20px;
}

#prod_nav ul, #prod_nav li:hover ul {
    position:absolute;
    left:-9999px;
    top:-9999px;
    width:0;
    height:0;
    margin:0;
    padding:0;
    list-style:none;

    top: auto;
    width: auto;
    height: auto;

#prod_nav li:hover li:hover a.fly, #prod_nav li:hover li:hover li:hover a.fly, #prod_nav li:hover li:hover li:hover li:hover a.fly, #prod_nav li:hover li:hover li:hover li:hover li:hover a.fly { 
    background: none;
}

Answer 1

更改left上的top和ul.sub定位。目前，当菜单悬停时，项目下拉列表ul.sub被告知从左侧移动170px，并从顶部移动-1px（向上1个像素）。

#prod_nav li:hover ul.sub {
    left: 0;
    top: 31px;
    background: #fff url(../images/productmenu-leftborder.gif) no-repeat left top;
    border: 1px solid #e2e2e2;
    border-left: 0;
    white-space: nowrap;
    width: 384px;
    height: auto;
    z-index: 300;
}
