Wrap every 4 posts in a custom wordpress loop with a div

Question

    <?php
      $args = array(

      'posts_per_page' => -1,
      'order' => 'DESC',
      'orderby' => 'menu_order'

      $the_query = new WP_Query( $args );
      if ( $the_query->have_posts() ) :
      while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

      <div class="col-3">

      </div>

   <?php

   wp_reset_postdata();
   ?>

Hi, I've never done this before. I'm trying to wrap every 4 posts in the loop above inside a <div class="row"></div>

This should sort you out

$args = array(
    'post_type' => 'college',
    'posts_per_page' => -1,
    'order' => 'DESC',
    'orderby' => 'menu_order'
);

$the_query = new WP_Query($args);
if ($the_query->have_posts()) :
    $counter = 0;
    while ($the_query->have_posts()) : $the_query->the_post();
        if ($counter % 4 == 0) :
            echo $counter > 0 ? "</div>" : ""; // close div if it's not the first
            echo "<div class='row'>";
        endif;
        ?>
        <div class="col-3">
            <?php the_title(); ?>
        </div>
        <?php
        $counter++;

    endwhile;
endif;
wp_reset_postdata();
?>
