Hello,

Yes. to achieve that, please follow the steps:
-go to file specular\includes\view\portfolio\loop-grid.php (if you have portfolio in grid layout)
-Find these lines(160)

 <div class="show_text">
       <h5><a href="<?php echo $link ?>"><?php echo get_the_title() ?></a></h5>
       <h6><?php echo esc_html($sort_clases) ?></h6>
  </div>  

and replace with these:

 <div class="show_text">
       <h5><a href="<?php echo $link ?>"><?php echo get_the_title() ?></a></h5>
       <h6><?php echo get_the_excerpt() ?></h6>
  </div>   

It will show text in the ‘Excerpt’ area of the portfolio item. If you are using masonry layout, do the same editing in file loop-masonry.php

Best regards!
