Hi,
Well, the system hasn't been made to handle that in the first place. It could be something to add in the future yes. However that's not a priority for us since most people don't create orders in the backend (remember that the main purpose of HikaShop is to allow you to sell your products on your website to your customers, not to create manually orders in the backend), and even for the merchants who most of them don't use options. In fact, you're the first one asking about that so far.
If you wanted to modify that yourself, you would have to :
- edit the file order / edit_products.php via the menu Display>Views in order to add the selection of the options in the popup.
- modify the saveForm function of the file administrator/components/com_hikashop/classes/order.php in order to handle the data sent by your modifications in the view file, and properly save that in the database.
