I'm used Field collection to add content type as field with unlimited but i want to alter this form fields for adding #autocomplete_path on each field
so i'm added the autocomplete for the first field as
$form['field_1']['und']['0']['field_1']['und']['0']['value']['#autocomplete_path'] = 'admin/path/autocomplete';
when i add more field collection field i want to added the same autocomplete for the next fields any solution for this ? Thanks in advance!.
