Noob question for get_terms

Hi everyone,

Sorry but this question is not really about the woocommerce plugin but I am just hoping that someone might help me here.

Basically I am trying to achieve a filter for brands. How can I filter the list of terms from the current product category? As of now all I know is to list all terms and this is fine for the shop page.

Thanks in advance

<?php
$args = array(
	'parent'	=>	0
);
$terms = get_terms( 'yith_product_brand', $args );
foreach( $terms as $term ):
	$term_link = get_term_link( $term ); ?>
	<li><a href="<?php echo esc_url( $term_link ); ?>"><?php echo $term->name; ?></a> <span class="count">(<?php echo $term->count; ?>)</span></li>
<?php
endforeach; ?>
