Hello!
I need your help!!! 
In my store I sell shoes. I have configurable products listed. Every configurable product has related simple products (each size is a simple product).
Configurable product: Visibility: Catalog, Search / Stock: 0 / In Stock
Simple product: Visibility: Not Visible Individually / Stock: X / In or Out of stock (depending)
For example Nikkee Aire is the configurable product. And associated products: Nikke Aire - Size 10, Nikke Aire - Size 11....
I've got the stock in each simple product and no in the configurable.
My problem is, when I use size filter, on the list I see configurable products with a simple product with this size.
How can I change the filter to show the products with simple product with this size(as it works now) and has stock (>0)?
I have Amasty Improved Navigation extension.
Thank you so much!
