Inserting option in dropdown list which fetches data from model

In my form I have

<?php echo $form->dropDownList($details,'current', CHtml::listData(Current::model()->findAll(), 'current', 'current'), array(

		 'empty'=>'Please Select',)); ?>

Now I get a dropdown with various options and Please select by default.

I want to insert one more option named Doesn’t Matter between Please select and the fields provided from list data

How will I do that?

This is how I did.

<?php echo $form->dropDownList($model,'nodes_id', CHtml::listData(array_merge(array('99'=>'test'),Nodes::model()->findAll(array('order' => 'name'))),'id','name'));?>
