基于html5代码实现折叠菜单附源码下载，效果逼真，非常方便使用，对html5折叠菜单感兴趣的朋友可以参考下 hmtl代码： 代码如下: <div class="container"> <div class="card-drop"> <a class='toggle' href="#"> <i class='fa fa-suitcase'></i> <span class='label-active'>爱编程</span> </a> <ul> <li class='active'> <a data-label="Everyting" href="#"><i class='fa fa-suitcase'></i> 爱编程</a> </li> <li> <a data-label="Design" href="#"><i class='fa fa-magic'></i> jQuery特效</a> </li> <li> <a data-label="UI-UX" href="#"><i class='fa fa-bolt'></i> CSS3特效</a> </li> <li> <a data-label="Print" href="#"><i class='fa fa-tint'></i> HTML5特效</a> </li> <li> <a data-label="Photography" href="#"><i class='fa fa-camera-retro'></i> 音效下载</a> </li> <li> <a data-label="Photography" href="#"><i class='fa fa-camera-retro'></i> flash动画</a> </li> </ul> </div> </div> js代码： 代码如下: (function ($) { var cards = $('.card-drop'), toggler = cards.find('.toggle'), links = cards.find('ul>li>a'), li = links.parent('li'), count = links.length, width = 100; li.each(function (i) { $(this).css('z-index', count - i); }; function setClosed() { li.each(function (index) { $(this).css('top', index * 4).css('width', width - index * 0.5 + '%').css('margin-left', index * 0.25 + '%'); }; li.addClass('closed'); toggler.removeClass('active'); } setClosed(); toggler.on('mousedown', function () { var $this = $(this); if ($this.is('.active')) { setClosed(); } else { $this.addClass('active'); li.removeClass('closed'); li.each(function (index) { $(this).css('top', 60 * (index + 1)).css('width', '100%').css('margin-left', '0px'); }; } }; links.on('click', function (e) { var $this = $(this), label = $this.data('label'); icon = $this.children('i').attr('class'); li.removeClass('active'); if ($this.parent('li').is('active')) { $this.parent('li').removeClass('active'); } else { $this.parent('li').addClass('active'); } toggler.children('span').text(label); toggler.children('i').removeClass().addClass(icon); setClosed(); e.preventDefault; }; }(jQuery)); 本文来源：https://www.wddqw.com/doc/382c51ac0622192e453610661ed9ad51f01d5497.html
