Drag & drop upload plugin, how to make it multiple I am trying to use this module to upload multiple files into a schemma that I created (in a separated module),

https://www.drupal.org/project/dragndrop_upload

$form['file'] = array (
'#type' =&gt; 'dragndrop_upload',
'#title' =&gt; 'Test',
'#description' =&gt; 'Test',
// This settings allows to drop multiple files at once.
'#attributes' =&gt; array (
        'multiupload' =&gt; '1',
'cardinality' =&gt; '10')
);


Seems to work great but it seems to ignore the 'multiupload' and the 'cardinality' arguments,

Any idea what am I missing?
It suggests you need this module; from the README file and project page;


  Multi-upload support will be enabled if Multiupload Filefield Widget
  module exists.
