Show custom fields in popup

Hi,

I made a custom post type with the ‘types‘-plugin.

There aslo include custum fields.

On a single page (single.php), I can adding displaying the custom fields with this code. Example for show up a website field:
types_render_field("website", array('output'=>'raw'));

Is it possible adding custom fields in the popup?

The only that shows up now is the title and the featured image.
You can see it here.

Regards,
Christophe
