multiSelect - 下拉菜单。当新选项添加

我使用一些代码从 http://abeautifulsite.net/blog/2008/04/jquery-multiselect/#demo multiSelect - 下拉菜单。当新选项添加

它看起来巨星，但我需要清除dropdwn并添加新的选项宽度改变。当我这样做时，宽度不变，并且展开。

我该如何添加选项宽度改变multidropdown的布局？

<fieldset data-role="controlgroup" style="width:200px"> 


    <select name="hobbies" style="padding:0px;" multiple="multiple" id="ddhobbies" data-native-menu="false"> 
     <option>Hobbies</option> 
     <option value="Reading">Reading</option> 
     <option value="Music">Music</option> 
     <option value="Movies">Movies</option> 
     <option value="Sports">Sports</option> 
     <option value="Cooking">Cooking</option> 
     <option value="Dancing">Dancing</option> 
     <option value="Social Service">Social Service</option> 
     <option value="Drawing/Painting">Drawing/Painting</option> 
     <option value="Other">Other</option> 

    </select></fieldset>
