1. 基础外观

    <span class="e_multiple">
    	<span class="e_multipleTop"><span></span></span>
    	<span class="e_multipleContent"><span><span>
    		<select multiple="multiple">
    			<option>选项</option>
    		</select>
    	</span></span></span>
    	<span class="e_multipleBottom"><span></span></span>
    </span>
    
  2. 扩展外观

    1. 加入功能区域

      <span class="e_multiple">
      	<span class="e_multipleTop"><span></span></span>
      	<span class="e_multipleContent"><span><span>
      		<select multiple="multiple">
      			<option>选项</option>
      		</select>
      	</span></span></span>
      	<span class="e_multipleFn">
      		<button type="button"><i class="e_ico-right"></i><span>添加</span></button>
      	</span>
      	<span class="e_multipleBottom"><span></span></span>
      </span>
      
    2. 自定义高度与宽度

      <span class="e_multiple" style="width:400px;">
      	<span class="e_multipleTop"><span></span></span>
      	<span class="e_multipleContent"><span><span>
      		<select multiple="multiple" style="height:156px;">
      			<option>选项</option>
      		</select>
      	</span></span></span>
      	<span class="e_multipleBottom"><span></span></span>
      </span>
      

      【注】高度的设置要求较高:如果是 utf-8 字符集,请设置为 14n+6,n 为整数;如果是 gbk 或 gb2312 字符集,请设置为 15n+6,n 为整数。如若不然,IE6/7 会出现高度问题。
