How to control error message under all radio buttons?

I have seen [url]http://jqueryvalidation.org/[/url]

How to put an error for radio items under all content as it seems it will show under the first radio button which is input field. Radio buttons are required fields.

Is this possible? which element defines an error message under all radio buttons?

I have code like:

[code=php]

<label class=”Title”>My label1:<em>*</em></label>
<div class=””>
<p><input type=”radio” name=”category1″ value=”1″ id=”” />1</p>
<p><input type=”radio” name=”category2″ value=”2″ id=”” />2</p>
<p><input type=”radio” name=”category3″ value=”3″ id=”” />3</p>
</div>

[/code]

Also in #JavaScript _↴
