Display the quantity field on the product page

Hi

In "General display options" is "Display the quantity field on the product page". I selected Ajax input.
I have 2 types of products. On first page product I need to show "Ajax input", but on the second product I need to hide it.

How can I do it? Any idea?

Hi,

Can you show me where do you want to hide it with some screenshots please ?

Thank you.

In first attached file is 6 products with "ajax input" fields.
In second screen file is page without "ajax input".

How Can I create both options on the one website?

Ok, I think that the quantity field isn't displaying because you're in a product listing, so you'll probably find your answer there :

You can edit the file listing_img_title of the view product via the menu Display->Views and add the code:
$this->params->set('show_quantity_field', 1);
at the beginning after the first <?php tag.
