form_dropdown -> optgroup validation issue

[eluser]xpix[/eluser]
Hi

I am using the form dropdown functionality like

Code:

<div class="formrow">&lt;?= form_label('Program: ', 'program') . form_dropdown('program',$programs_list);?&gt;</div>

The output is:

Code:

<div class="formrow"><label for="program">Program: </label><select name="program">
<optgroup label="0">
</optgroup>
<option value="113">aaaaaa</option>
<option value="114">bbbbbb</option>
<option value="116" selected="selected">ccccc</option>
<option value="115">ccccc</option>
</select></div>

The page doesn't validate on w3.org because of the optgroup. As you can see I have no need for the optgroup. Is there a way I can remove this tag?

Thx
