how to add Active Admin form input :html {multiple => ""}?

ActiveAdmin form:

my problem: I can not get a form with multiple choice files(

I tried: 

      ActiveAdmin.register Foto do: 
       form :html => { :multipart => true } do |f|
         f.inputs "Upload" do
          f.input :foto, :as => :file
         end
         f.actions
       end
      end

this does not work, then I made a simple html page with two forms:

    <!DOCTYPE doctype html>
    <html>
     <head>
     </head>
     <body>
      <!--**not** work multiple choice files-->
      <form accept-charset="UTF-8" action="#" enctype="multipart/form-data" method="post">
        <input id="image" name="image" type="file"/>
      </form>

      <!--**great** work multiple choice files-->
      <form accept-charset="UTF-8" action="#" method="post">
        <input id="image" name="image" type="file" multiple=""/>
      </form>

     </body>
    </html>
