Sure.
Repeater Template:
<div class="col-sm-6 col-md-6 col-lg-4 ajax-item"<?php if (! has_post_thumbnail() ) { echo ' class="no-img"'; } ?>>
<div class="ajax-item-border">
<?php global $post; ?>
<?php if ( has_post_thumbnail() ) { ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
<?php the_post_thumbnail('large'); ?>
</a>
<?php } ?>
<h3>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
<?php the_title(); ?>
</a>
</h3>
<?php $term_list = wp_get_post_terms($post->ID, 'portfolio-category', array("fields" => "all")); ?>
<p class="portfolio-cat <?php echo $term_list[0]->slug ; ?>">
<a href="<?= esc_url(home_url('/')); ?>portfolio-category/<?php echo $term_list[0]->slug ; ?>">
<?php echo $term_list[0]->name ; ?>
</a>
</p>
<?php the_excerpt(); ?>

</div>
