If you are wanting to do this on the client side via JavaScript, you
won't be using Struts 2 server-side tags. Look around for JavaScript
tutorials about adding form elements. Perhaps one of the popular
JavaScript frameworks like Dojo will be of help here.

Hi!
I have the "Poll" and "PollOption" objects. In my form, I want to be able to
add more options to my Poll via javascript code.
The problem is I don't know how to put the fields in my form. The way I try
is not binding the form data with Action properties (a "public Poll poll;"
with getter and setter).
My PollAction.poll.pollOptions is null after form submission.
Can you help me?
Sample code I trying:
Poll {
Integer id;
String question;
List <PollOption> options;
}
PollOption {
Integer id;
String option;
Integer totalVotes;
}
My form (freemarker):
<@s.textfield name="poll.name" />
<@datepicker name="poll.startDate"/>
<@datepicker name="poll.finishDate"/>
<@s.textarea name="poll.question" rows="5"/>
<table id="tableAddPollOptions" cellspacing="0" width="100%">
<tbody>
<#assign rowIndex = 0>
<#if poll.pollOptions??>
<#list poll.pollOptions as option>
<tr>
<td>
<@s.hidden name="poll.pollOptions[${rowIndex}].id" />
<@s.textfield name="poll.pollOptions[${rowIndex}].option" />
<input type='button' onclick='dropMyRow(this);' value='remove option'>
</td>
</tr>
<#assign rowIndex = rowIndex
+ 1>
</#list>
</#if>
</tbody>
</table>
<br />
<a href="javascript:addPollOption();">add option</a>
Thanks,
Luciano Costa
