Codeigniter Form Extend Helper

Im trying to do chained select using jquery chained, but codeigniter echo form dropdown does not allow individual assignment of CLASS.

I would like to assign CLASS to each list like the example below. 

<select name="hardware">
<option class="printer" value="" selected="selected"></option>
<option class="printer" value="EPSON">EPSON</option>
<option class="printer" value="HP">HP</option>
<option class="hdd" value="WD">WD</option>
<option class="hdd" value="SEAGATE">SEAGATE</option>
</select>

and here is the codeigniter form dropdown

VIEW PAGE: 

 <form action="" method="">
    $select = 'hardware';
    echo form_dropdown('hardware', $hardware,set_value('hardware',$this->input->post('hardware'))); ?>  
 </form>

I have changed the select form to this. 

<select name="supplier">
<?php foreach($supplier as $row){ ?>
<option value="<?php echo $row['supplier'];?>"><?php echo $row['supplier'];?>  
</option>
<?php }?>
</select>

how can i return the selected value after a failed validation?

what you want to do, you will have to create your own helper,See "Extending Helpers" here in the docs. I would do what is says and copy a "MY_helper.php" version to your application folder; don't mess with the core unless you really have to.

http://ellislab.com/codeigniter/user-guide/general/helpers.html

You could use the values array and set a class and item in an array (and change the foreach near line 327 in the helper) or pass another array and check it in the foreach.

This is not possible using the form_dropdown() because codeigniter is not allowing any parameter to set the "extra" attributes like class in the option tag.

Check this function : this is the core function form_dropdown() : 

function form_dropdown($name = '', $options = array(), $selected = array(), $extra = '')
    {
        if ( ! is_array($selected))
        {
            $selected = array($selected);
        }

        // If no selected state was submitted we will attempt to set it automatically
        if (count($selected) === 0)
        {
            // If the form name appears in the $_POST array we have a winner!
            if (isset($_POST[$name]))
            {
                $selected = array($_POST[$name]);
            }
        }

        if ($extra != '') $extra = ' '.$extra;

        $multiple = (count($selected) > 1 && strpos($extra, 'multiple') === FALSE) ? ' multiple="multiple"' : '';

        $form = '<select name="'.$name.'"'.$extra.$multiple.">\n";

        foreach ($options as $key => $val)
        {
            $key = (string) $key;

            if (is_array($val) && ! empty($val))
            {
                $form .= '<optgroup label="'.$key.'">'."\n";

                foreach ($val as $optgroup_key => $optgroup_val)
                {
                    $sel = (in_array($optgroup_key, $selected)) ? ' selected="selected"' : '';

                    $form .= '<option value="'.$optgroup_key.'"'.$sel.'>'.(string) $optgroup_val."</option>\n";
                }

                $form .= '</optgroup>'."\n";
            }
            else
            {
                $sel = (in_array($key, $selected)) ? ' selected="selected"' : '';

                $form .= '<option value="'.$key.'"'.$sel.'>'.(string) $val."</option>\n";
            }
        }

        $form .= '</select>';

        return $form;
    }
