Chained Dropdown Inside Multiplier

Dear all,

How to user chained dropdown on mutliplier?. We know that multiplier has unique field name, for example : fileupload[__N__][provinsi]. When I tried to implement chained dropdown (province and district) with district db read condition :

 <?php
  return array( 'id_prov' => $form->fileupload[__N__][provinsi]);
  ?> 

and custom code

<?php
$options = array();
if ( !$form->data['Kabupaten'] || count($form->data['Kabupaten']) < 1 ) {
  // no result was found
  $options[] = '-Pilih Kabupaten-';
} else {
  foreach ( $form->data['Kabupaten'] as $d ) {
    $options[$d['id_kabupaten']] =  $d['nm_kab'];
  }
}
echo json_encode($options);
?>

Maybe I miss something?
Thanks

Hi Yudhizth,

You might be able to get this to work with some careful custom coding but I don't think that I would even try unless I had a very clear head.

Is the list of districts isn't too long it might work to hard code that in the drop-down events tab.

Thanks Bob

Unfortunately, districts has more than 600 list😟 .

Someone could help me? 😢

Hi Yudhizth,

Please see my previous post - this will need careful custom coding to get it to work - if that is possible,

Bob
