HTML JSP code creation question

Question

I have a submit button, created from - basically when this is clicked I want a groupbox to appear below where the submit button is....any suggestions?

I've tried to get the request given of from this click however it doesn't help me. I thought the logic would be similar to this:

<form>
   <input type="checkbox" name="group" value="Yes" />Yes
   <input type="checkbox" name="group" value="No" /> No
   <input type="submit" value="submit" />
</form>
<%
   String[] select = request.getParameterValues("group");
  /* Add code creation here */
%>

Any suggestions or examples you can think of?

Thanks greatly, U.

First replace the checkboxes by radio buttons. Right now it's possible to check both Yes and No. This makes no sense.

<form>
   <input type="radio" name="group" value="Yes" /> Yes
   <input type="radio" name="group" value="No" /> No
   <input type="submit" value="submit" />
</form>

Then, use JSTL <c:if> tag to conditionally display content depending on parameters and/or other scoped variables in EL.

<c:if test="${param.group == 'Yes'}">
    <p>Write here HTML code which you'd like to show when 'Yes' is chosen.</p>
</c:if>
<c:if test="${param.group == 'No'}">
    <p>Write here HTML code which you'd like to show when 'No' is chosen.</p>
</c:if>
