Sorry forgot to show you what I have tried so far. I found someone asking a similar question in forum https://support.advancedcustomfields.com/forums/topic/checkbox-how-to-display-all-item-as-check-uncheck/

I used the code in the reply marked as solved, but are getting errors.

Here’s my PHP code:

<?php
$value = get_field('service_options');
$field = get_field_object('service_options');
$choices = $field['choices'];

if( $field ) :
?>
<ul>
   <?php
		
   foreach($choices as $value => $label) :
      if( in_array($value, $values) ) :
         $class = ' class="selected"';
      else :
	 $class = '';
      endif;
      echo '<li' . $class . '>' . $label . '</li>';
   endforeach;
		
   ?>

</ul>
<?php endif; ?>

But I’m getting the following warning for each option:

Warning
: in_array() expects parameter 2 to be array, null given in …

In addition to the warning on each item, , the class selected isn’t being added to the options that were selected.
