I want to add class to the magento admin custom grid filter dropdown.
I have dropdown in one filter column and I dont want to use JS to reduce client side load.
Is there anyway to add class while preparing column to the grid.php?
$this->addColumn('mfg', array( 'header' => Mage::helper('manufacturer')->__('Manufacturer'), 'index' => 'mfg_id', 'filter_index' => 'SFOIA.mfg_id', 'type' => 'options', 'options' => $this->getManufacturersWithExtraOption(), 'filter_condition_callback' => array($this, '_manufacturerCallback'), ));
I dont want add class to the column - Need class to the filter dropdown only. just in to its html
