Dynamic options checkbox group

Hello I have a event that runs correctly: A dropdown with JSON after read database values:

<?php
$results = array();
$results[] = 'coles';
foreach ( $form->data['coles'] as $v ) {
  $results[$v['co_registro']] = $v['co_nombre'];
}
echo json_encode($results);
?>

Is posible put the same values to a checkbox group field??
Thanks

Hi ideagrup,

Do you want to create this using AJAX after the form is loaded? If so then you can't use the built-in AJAX methods for a CheckBox group but you could do it with custom JavaScript.

Or do you want to set this up before the form loads - in that case, yes you can do it using the Dynamic Data tab of a Checkbox group action - but the results have to be formatted a bit differently.

Yes, first case.
I need after the form is loaded.

Do you know some sample og this in JavaScript used into crhonoforms??
