<select id="firstpreselected" size="10" multiple="MULTIPLE" style="height: 300px;

                            width: 200px;">
</selected>

<script type="text/javascript">
         $(function () {  
             $("#btn_addfirst").bind("click", function () {
                 $("#firstpreselected option:selected").each(function () {
                     $("#firstselected").append("<option value=\"" + $.trim($(this).val()) + "\">" + $.trim($(this).html()) + "</option>");

                 });
             });
             $("#btn_removefirst").bind("click", function () {
