Thank you for your replying, but this is not I want exactly, what I need:

a dropdown list (NOT by selecting with check options),in order to give an ability for client to select a Qty. value from a dropdown list (0.25 to 10 for ex), and then calculated (by multiplication the price with the Qty).

I don't want to put predefined values for every Qty. in a list (its price) manually (this is a tough & not practical)

thank you

We apologize for inconvenience. If I understand correctly, you wanted to use fraction numbers on the Quantity dropdown list option in your Order form.

Unfortunately, this is not possible at this time. You can only use whole numbers in the Qty option of the order form.

The possible workaround is to make a custom order form using regular Dropdown list field  (not the one in payment/order form).
