如何在列表项上悬停时创建侧边菜单

Question

我目前有这样的下拉列表：

我想要的是，如果从第1个下拉菜单等下拉菜单中的每个列表项目等等，那么点击这些项目时会有另一个下拉菜单。就像单击ASPIRE时一样，然后会出现另一个下拉列表。 怎么做？

这是我的代码：

CSS部分：

@import url(http://fonts.googleapis.com/css?family=Open+Sans:400,600,300);
@charset "UTF-8";
/* Base Styles */
#cssmenu,
#cssmenu ul,
#cssmenu li,
#cssmenu a {


margin: 0;
  padding: 0;
  border: 0;
  list-style: none;
  font-weight: normal;
  text-decoration: none;
  line-height: 1;
  font-family: 'Open Sans', sans-serif;


font-size: 14px;
  position: relative;
}
#cssmenu a {
  line-height: 1.3;
}

#cssmenu {
  width: 300px;
 margin-left: 90px;  background: #A3FFFF;
  -webkit-border-radius: 4px;
  -moz-border-radius: 4px;
  border-radius: 3px;
  padding: 3px;


 -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.6);
  -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.6);
  box-shadow: 0 0 5px rgba(0, 0, 0, 0.6);
}


#cssmenu > ul > li {
  margin: 0 0 3px 0;
}
#cssmenu > ul > li:last-child {
  margin: 0;
}
#cssmenu > ul > li > a {
  font-size: 15px;
  display: block;
  color: 

#ffffff;
  text-shadow: 0 1px 1px #000;
  background: #A3FFFF;
  background: -moz-linear-gradient(#565656 0%, #323232 100%);
  background: -webkit-gradient

(linear, left top, left bottom, color-stop(0%, #565656), color-stop(100%, #323232));
  background: -webkit-linear-gradient(#565656 0%, #323232 100%);


background: linear-gradient(#565656 0%, #323232 100%);
  border: 1px solid #000;
  -webkit-border-radius: 4px;
  -moz-border-radius: 4px;
  border-radius: 4px;
}
#cssmenu > ul > li > a > span {
  display: block;
  border: 1px solid #666666;
  padding: 6px 10px;
  -webkit-border-radius: 4px;
  -moz-border-radius: 4px;


border-radius: 4px;
  font-weight: bold;
}
#cssmenu > ul > li > a:hover {
  text-decoration: none; font-weight: bold;
}
#cssmenu > ul > li.active {
  border-bottom: 

none; 
}
#cssmenu > ul > li.active > a {
  background: #47A3FF;
  background: -moz-linear-gradient(#47A3FF 0%, #47A3FF 100%);
  background: -webkit-gradient

(linear, left top, left bottom, color-stop(0%, #47A3FF), color-stop(100%, #47A3FF));
  background: -webkit-linear-gradient(#47A3FF 0%, #47A3FF 100%);


background: linear-gradient(#47A3FF 0%, #47A3FF 100%);
  color: #fff;
  text-shadow: 0 1px 1px #fff;
  border: 1px solid #47A3FF;
}
#cssmenu > ul > li.active > a 

span {
  border: 1px solid #47A3FF;
}
#cssmenu > ul > li.has-sub > a span {
  background: url(images/icon_plus.png) 98% center no-repeat;
}
#cssmenu > ul > li.has

-sub.active > a span {
  background: url(images/icon_minus.png) 98% center no-repeat;
}

/* Sub menu */
#cssmenu ul ul {
  padding: 5px 12px;
  display: none;
}
#cssmenu ul ul li {
  padding: 3px 0;
}
#cssmenu ul ul a {
  display: block;
  color: #191975;


font-size: 13px;
  font-weight: bold;
}
#cssmenu ul ul a:hover {
  color: cornflowerblue; font-weight:bold;
}

使用Javascript：

( function( $ ) {
$( document ).ready(function() {
$('#cssmenu > ul > li > a').click(function() {
  $('#cssmenu li').removeClass('active');
  $(this).closest('li').addClass('active'); 
  var checkElement = $(this).next();
  if((checkElement.is('ul')) && (checkElement.is(':visible'))) {
    $(this).closest('li').removeClass('active');
    checkElement.slideUp('normal');
  }
  if((checkElement.is('ul')) && (!checkElement.is(':visible'))) {
    $('#cssmenu ul ul:visible').slideUp('normal');
    checkElement.slideDown('normal');
  }
  if($(this).closest('li').find('ul').children().length == 0) {
    return true;
  } else {
    return false;   
  }     
});
});
} )( jQuery );

Html：

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
   <script src="script.js"></script>

<div id='cssmenu'>
<ul>



<li class='has-sub'><a href='#'><span>CENTRAL COMPLIANCE</span></a>
