Styling drop-down menu with jQuery (link vs style problem)

Styling drop-down menu with jQuery (link vs style problem)

Hi,
I am very new to jQuery (5 hours use).
What I am trying to do is to style a drop-down box.
Here is the code:

Part 1
  1. <script  type="text/javascript">
    $(document).ready(function() {
        $('#Items').selectbox();
    });
    </script>






Part 2
  1.   <div id="menu" >
            <select name="Items" id="Items">
              <option onClick="window.location='index.php'">Index</option>
             </select>
     
      </div>




Part 3 CSS
  1. div.selectbox-wrapper ul {
      list-style-type:none;
      margin:0px;
      padding:0px;
    }

    div.selectbox-wrapper ul li.selected {
      background-color: #EAF2FB;
    }


    div.selectbox-wrapper ul li.current {
      background-color: #CDD8E4;
    }


    div.selectbox-wrapper ul li {
      list-style-type:none;
      display:block;
      margin:0;
      padding:2px;
      cursor:pointer;
    }


    .selectbox
    {
        margin: 0px 5px 10px 0px;
        padding-left:2px;
        font-family:Verdana, Geneva, Arial, Helvetica, sans-serif;
        font-size:.5em;
        width : 190px;
        display : block;
        text-align:left;
        background: url('bg_select.png') right;
        cursor: pointer;
        border:1px solid #D1E4F6;
        color:#333;
    }









































So the styling part works great but at this point my link does not work.
When i change #Items in part one to anything else, my links work but styling does not.
Of coursei am including two more files in this. (if it would help I can post them here but from what I see this has to do with the way CSS is being used with jQuery.)


Thank you
