<ul class="companymenuul"><li class="companymenuli aactive"><a class="alisting">首页</a></li><li class="companymenuli"><a class="alisting">产品类别<b class="caret"></b></a><ul><li>1</li><li>2</li><li>3</li><li class="companymenuli"><a class="alisting">公司简介<b class="caret"></b></a><li class="companymenuli"><a class="alisting">联系人</a>

我想在产品类别

悬停时打开

解决方案

您是否正在寻找类似的东西?小提琴

给你的子菜单一个类并添加display:none;.在你可以悬停之后 display:block;

所以你有这样的事情:

HTML:

<li class="companymenuli"><a class="alisting">产品类别<b class="caret"></b></a><ul class="子菜单"><li>1</li><li>2</li><li>3</li>

CSS:

.submenu{显示:无；}panymenuli:hover >ul{显示:块；}

要删除项目符号，只需将 list-style-type:none; 添加到您的 submenu li 标签.这是您更新的小提琴:

Hi I am making menu and submenu. I have made menu with all effect. I want to open submenu on hover of menu item, but it's not opening; it shows me already open.

My JSFiddle

#companymenu { background-color: #999; height:35px; width:100%; margin-top: -10px; } panymenuul { list-style-type: none; } panymenuli { float: left; display:block; line-height: 35px; padding: 0 15px; } .alisting { color:#000; text-decoration:none; } .aactive { color: #333; background-color: #fff; border-top: 2px solid #999; margin-top: -2px; } panymenuli a:hover { color:#C63; text-decoration:none; cursor:pointer; padding-top:10px; padding-left:24px; padding-right: 23px; padding-bottom: 11px; background-color: #fff; border-top: 2px solid #999; margin-top: -2px; } .caret { display: inline-block; width: 0; height: 0; vertical-align: top; border-top: 4px solid #fff; border-right: 4px solid transparent; border-left: 4px solid transparent; content:""; margin-top: 15px; margin-left: 5px; border-bottom-color: #fff; filter: alpha(opacity=100); background-image:url(images/topnav-arrow-down-white-ie6.png)no-repeat 0 0 transparent; _display: inline; _zoom: 1; _width: 7px; _height: 4px; _margin-top: 8px; _margin-left: 5px; _line-height: 4px; _border: none; _vertical-align: baseline; }

<div id="companymenu"> <ul class="companymenuul"> <li class="companymenuli aactive"><a class="alisting">Home</a></li> <li class="companymenuli"><a class="alisting">Product Categories<b class="caret"></b></a> <ul> <li>1</li> <li>2</li> <li>3</li> </ul> </li> <li class="companymenuli"><a class="alisting">Company Profile <b class="caret"></b></a> </li> <li class="companymenuli"><a class="alisting">Contacts</a> </li> </ul> </div>

I want to open <ul> on hover of Product Categories <li>

解决方案

Are you looking for something like this? Fiddle

Give your submenu a class and add display:none; to it. After you can give your hover display:block;

So you have something like this:

HTML:

<li class="companymenuli"><a class="alisting">Product Categories <b class="caret"></b></a> <ul class="submenu"> <li>1</li> <li>2</li> <li>3</li> </ul> </li>

CSS:

.submenu{ display:none; } panymenuli:hover > ul{ display:block; }

EDIT:

For removing the bullets just add list-style-type:none; to your submenu li tag. Here your updated fiddle:
