Theme Business-One

Hello, I’m customizing the Business -One theme for a website.
In the portfolio, if you click into a job of portfolio there any way to projects relating to the same category?

Copy/paste file section-portfolio.php:

<?php global $business;

if(have_posts()):

if(get_posts(array(‘post_type’ => ‘portfolio’ , ‘posts_per_page’ => 18))){ ?>

<!– PORTFOLIO –>
<section class=”section-portfolio clearfix” id=”portfolio”>

<header class=”heading-wrap”>

<h2 class=”section-head”><?php _e(‘portfolio’,’business-one’); ?></h2> <!– end section-head –>

<?php if(isset($business[‘portfolio-text’])){

if($business[‘portfolio-text’]){ ?>

<div class=”heading-line”></div>

<p class=”heading-desc”><?php echo $business[‘portfolio-text’]; ?></p>

<?php } } ?>

</header> <!– end heading-wrap –>

<div class=”portfolioContainer clearfix”>

<?php query_posts(‘post_type=portfolio’); ?>

<?php while(have_posts()):the_post(); ?>

<div class=”h-product col-sm-6 col-md-4 col-lg-3″>

” class=”u-url”>
<?php the_post_thumbnail(); ?>

<h4 class=”p-name”><?php the_title(); ?></h4>
</div>

<?php endwhile; ?>

<?php wp_reset_query(); ?>

</div>

</section>
<!– END PORTFOLIO –>

<?php } ?>

<?php endif; ?>

Thanks ??
