Fill a combobox dynamically on selecting rom another combobox

Question

Hello,
In my JSP, I hace 2 combo box, 1 with single selection (typeCmb) and 1 with multiple selction (itemsCmb).
On selecting a item from typeCmb, I want to load contents of itemCmb. The contents of itemCmb will have to loaded dynamically. I can't get the concept to implement this. Can anyone help me how to achieve the goal. Both items belong to same form.
Any help is appreciated.
Thanks,

Then what do I do. This is what I have coded :
   function selectionType() {
        document.sendform.listSelect.options.length = 0;
        var index = document.forms[0].emailtype.selectedIndex;  // Index of emailtype
        var data = document.forms[0].emailtype.options[index].value;    // Value of emailtype
        <%  String s="";
            int j = 0;    %>
        if (data == "TestMail") {
           size = <%=testUsers.size()%>;
           ai = 0;
           <%
            s = "";
            AdminUserBean ab = null;
            for (j=0; j < testUsers.size(); j++) {
                 ab = (AdminUserBean)testUsers.get(j);
                 s = ab.getUsername() + " : "  + ab.getEmail();
            %>
                document.forms[0].listSelect.options[ai] = new Option("<%= s%>", "<%=ab.getEmail()%>");
                ai = ai + 1;
            <%
                ab = null;
            %>
        } else if(data == "CampaignMail") {
           size = <%=domains.size()%>;
           ai = 0;
           <%
            s="";
            for (j=0; j < domains.size(); j++) {
                s = domains.get(j);
            %>
                document.forms[0].listSelect.options[ai] = new Option("<%=s%>", "<%=s%>");
                ai = ai + 1;
            <%
            %>
<select onmouseout="window.status=''; return true;" onmouseover="window.status='Select Mail Type'; return true;" onchange="selectionType()" style="width: 270px; font-weight: bold;" name="emailtype">
     <option value="TestMail" selected="true">Test Mail</option>
     <option value="CampaignMail">Campaign Mail</option>
