quick shopping form

-- url of the page with the problem -- : www.kaishii.com.tw/order.php
-- HikaShop version -- : 2.3.3
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.5.16
-- Browser(s) name and version -- : Chrome 37.0.2062.124

Is it possible to build a quick shopping form like this in Hikashop?
www.kaishii.com.tw/order.php

Customer can select multiple products in one single form, and after pressing the “add to cart” button, all the selected products goes into shopping cart simultaneously.

Thank you for helping me.

Hi,

Yes it's possible, in the menu/module settings select the value "Global on listing" for the option "Display the quantity field on the product page" in Configuration > Main > Product.
