jQuery自适应导航菜单效果代码

使用方法：

引用CSS样式

<link rel="stylesheet" href="css/pgwmenu.css">

自定义样式

.pgwMenuCustom { background: #f1941c; height: 40px; position: relative; list-style: none }
.pgwMenuCustom ul { list-style: none; white-space: nowrap; margin: 0; padding: 0 }
.pgwMenuCustom .pm-links.mobile, .pgwMenuCustom .pm-viewMore>ul { background: #f1941c; box-shadow: 2px 2px 4px #777; position: absolute; left: 0; top: 100%; z-index: 1000 }
.pgwMenuCustom .pm-links.mobile li, .pgwMenuCustom .pm-viewMore>ul>li { display: block; clear: both; width: 175px }
.pgwMenuCustom li { float: left }
.pgwMenuCustom a { display: block; color: #fff; line-height: 40px; padding: 0 30px; text-decoration: none }
.pgwMenuCustom a.selected { background: #e5601d }
.pgwMenuCustom li a:hover { background: #e86f2e; text-decoration: none }
.pgwMenuCustom .pm-dropDown, .pgwMenuCustom .pm-viewMore, .pgwMenuCustom .pm-viewMore>ul { display: none }
.pgwMenuCustom .pm-dropDown a { display: inline-block; background: #e86f2e }
.pgwMenuCustom .pm-dropDown a.active, .pgwMenuCustom .pm-viewMore a.active { background: #e5601d }
.pgwMenuCustom .pm-dropDown span.icon, .pgwMenuCustom .pm-dropDown span.black { background: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABYAAAAWCAYAAADEtGw7AAAABGdBTUEAALGPC/xhBQAAAAlwSFlzAAAOvgAADr4B6kKxwAAAABZ0RVh0U29mdHdhcmUAcGFpbnQubmV0IDQuMDvo9WkAAABpSURBVEhL7ZPLCcAwDEM9jefI/ks1Hyj2QbiGSLcKHggl8sEktjTc/WGyZxo6YKAbrFzFoav3/hdhmsrlijBN5XJFmKZyuSJMU7lcsfV/kIN0FRJgyACGDGDIAIYMpK8CHt6iG6xZhY0JIJ+6AHGbUFsAAAAASUVORK5CYII=) no-repeat; display: block; height: 22px; width: 22px; margin: 9px 5px }

.pgwMenuCustom .pm-viewMore { display: none; position: relative }
.pgwMenuCustom .pm-viewMore>a { display: inline-block }
.pgwMenuCustom .pm-viewMore>ul { left: auto; right: 0 }

.pgwMenuCustom .pm-viewMore span.black { border-color: #000 transparent; border-style: solid; border-width: 8px 6px 0; margin-left: 3px; display: inline-block }

引入jQuery库文件、插件JS文件

<script type="text/javascript" src="js/jquery-1.8.3.min.js">script>
<script type="text/javascript" src="js/pgwmenu.min.js">script>

插件初始化、配置

$(function() {
	$('.pgwMenu').pgwMenu({
		dropDownLabel: '菜单',
		viewMoreLabel: '更多'
	});
	$('.pgwMenuCustom').pgwMenu({
		mainClassName: 'pgwMenuCustom',
		dropDownLabel: '菜单',
		viewMoreLabel: '更多'
	});
});
