Take a look at the documentation: https://www.advancedcustomfields.com/resources/checkbox/
This example works, if you selected “Both (Array)” in “Return Format” option
<?php
$field_name = "service_for";
$fields = get_field($field_name);
if($fields){
foreach ($fields as $field){
echo '<div class="col-xs-4 col-lg-3"><strong>' . $field['label'] . ':' . '</strong></div>';
echo '<div class="col-xs-8 col-lg-9">' . $field['value'] . '</div>';
}
}
?>
