I would like to display default available options on product page and quick view same as CS-CART V.3
Example :
Product "A" I have 3 size are S (0 piece - position 1), M (2 pieces - position 2) and L (1 piece - position 3)
When the customer click on product. it'll be display (position 1) "No products with the selected options in stock".
It should be display available options first.
How can I config to display default available options?
