JSP drop down problem; iam confused

Question

Hi All,
can anybody help me out in creating this jsp page. Iam confused what to do and where to start building this page.
Here is what i need to do :
This new page will have two list boxes side by side and will have two arrows in between. In the left hand box will be a list of "Firm Divisions" that can be selected by using the mouse and arrow button. The user will be able to select one or more of the "Firm Divisions". After the desired "Firm Divisions" are selected the user will click on the SUBMIT button and a message will appear to confirm the request has been sent. The user will then click on the OK button and will be brought back to the previous screen( i.e Pop up a conformation box with a required OK button ).
CAN ANYBODY HELP ME IN BUILDING THIS JSP PAGE. I can do the backend processes but iam stuck creating this jsp page.

Answer 1

yes, put at least 2 buttons(or images with <a href>) one for remove and the other for add, and call a JavaScript function while clicked (onClick event)= onClick="javascript:removeFromList();"
function addToList(){
form=document.form;
itemText=form.right_list.options[form.right_list.selectedIndex].text;
itemValue=form.right_list.options[form.right_list.selectedIndex].value;
form.right_list.options[form.left_list.selectedIndex]=new Option(itemText,itemValue);
function removeFromList(){
form=document.form;
if (form.left_list.selectedIndex!=-1){
form.left_list.options[form.left_list.selectedIndex]=null;
got the idea?
Nelson.
