Question

请考虑本网站：http://indivar.biz/test/balkar/。我在“住宅项目”选项卡上创建了子菜单下拉菜单，但是当我们将导航选项卡“住宅项目”悬停时，它会在导航灰色区域内显示子下拉菜单，但我希望它显示在灰色区域之外，即完整内容宽度的导航。

以下是相关代码：

CSS

.left-section {
    float: left;
    overflow: hidden;
    width: 220px;
}

#nav {
    background: none repeat scroll 0 0 #E4E4E4;
    position: relative;
    z-index: 9999;
}
#nav ul {
    margin: 0 auto;
    padding: 6.5px 0;
    width: 197px;
}
#nav ul li {
    background: url("../images/nav-line-bottom.jpg") repeat-x scroll center bottom transparent;
    height: 29px;
    line-height: 34px;
}
#nav ul li a {
    color: #242121;
    display: block;
    font-size: 15px;
    height: 30px;
    line-height: 23px;
    margin-top: 5px;
    text-decoration: none;
}
#nav ul li a.home {
    background: url("../images/nav-icons.png") no-repeat scroll 0 0 transparent;
    padding-left: 32px;
}
#nav ul li a.about {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -32px transparent;
    padding-left: 32px;
}
#nav ul li a.services {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -63px transparent;
    padding-left: 32px;
}
#nav ul li a.resi-proj {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -96px transparent;
    padding-left: 32px;
}
#nav ul li a.comm-proj {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -130px transparent;
    padding-left: 32px;
}
#nav ul li a.career {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -161px transparent;
    padding-left: 32px;
}
#nav ul li a.faq {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -195px transparent;
    padding-left: 32px;
}
#nav ul li a.nri {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -228px transparent;
    padding-left: 32px;
}
#nav ul li a.cont {
    background: url("../images/nav-icons.png") no-repeat scroll 0 -262px transparent;
    padding-left: 32px;
}
#nav ul li ul {
    background: none repeat scroll 0 0 #CC0000;
    display: none;
    left: 150px;
    position: absolute;
    top: 135px;
    width: 220px;
    z-index: 9999;
}
#nav ul li:hover ul {
    display: block;
}
#nav ul li ul li a {
    color: #FFFFFF;
    display: block;
}

HTML

<div class="left-section">
      <!--logo div ends-->
      <div class="clear"></div>
      <div class="margin-top" id="nav">

      </div>

    </div>

Answer 1

从.left-section DIV中删除溢出：隐藏。写得像这样：

.left-section {
    float: left;
    width: 220px;
}

#nav ul li ul {
    background: none repeat scroll 0 0 #CC0000;
    display: none;
    left: 220px;
    position: absolute;
    top: 135px;
    width: 220px;
    z-index: 9999;
}

你有一些问题需要解决，首先你的子菜单加载远离你的菜单项，我建议你把它放在你的父菜单项旁边，如下所示：

#nav ul li  {
    position:relative;
}

#nav ul li ul {
    background: none repeat scroll 0 0 #CC0000;
    display: none;
    left: 100%; /* change here */
    position: absolute;
    top: 0; /* change here */
    width: 220px;
    z-index: 9999;
}

此外，您使用属性.left-section将您的子菜单隐藏在overflow:hidden内，删除该子菜单，它将全部显示。
