Goods on demand

[Mesitop]

I'm not sure about this topic title but the problem is following. I have some products that are not in store always but customers have to order these. I want  that the customer could see text " Telli" ("Order") instead of "Laos" ("Available"). and that the button "Lisa ostukorvi" ("Add to basket") is active. So if someone wants to buy for example a honey extractor then he knows that it's not in the store but he has to order it. At the moment Prestashop does not allow the combination of settings:

1. product is not in the store (quantity is "0")

2. "Add to basket" button is active

 

Or, to be exact - it allows this combination but then shows "Available" under the price 

 

Please help!

Yesterday I was a bit in a hurry so I'll try to explain better what is my problem...

 

I have some products - like honey extractors and other beekeeping equipment - that one can buy only by ordering (delivery: ca 14 days). At the moment Prestashop acts like following: when in the backoffice I set one of these products quantity to "0" and at the same time I set that it's allowed to order (by default it's not allowed to order products that are out of stock), then in the product list Prestashop automatically shows this product as "Available" and you can add it to the  shopping cart (the button "Add to cart" is active) Actually this is stupid (the quantity is set to "0" but for the Prestashop the product is still "available"). I want that when I set the quantity to "0", Prestashop would display "Out of stock" but at the same time the button "Add to cart" remains active. How to achieve this?

 

Thank you in advance.
