Please help to find a file

[Darko F.]

Hi all

I just want to add few classes to these files below for category view

<?php echo $this->orderByList['orderby']; ?>
I find these file in com_virtuemart/sublayouts ->  orderby.php

But I can't find these file here:
<?php echo $this->orderByList['manufacturer']; ?>

I'm using VirtueMart 4.0.4 10688

Can someone help?

Thank you.
