On our test site, i have all product stock set to zero, except for the single product at this link: www.testing.mojooutdoors.com/spinning-wi...ys/mojo-king-mallard

Likewise, the product options also have zero stock, but I can still set them to "yes" for adding it to the main product. However, once you click add to cart, it display "cannot add product to cart." Is there anyway to hide the product option if there is zero stock for the product corresponding to that option? For example, how would i hide the "6-Volt Battery Charger" product option if it has zero stock?

I have 3.4.0 installed, but the options still show no/yes even though the product options are out of stock.

Really just need it to say "out of stock" or even hide them completely if the product option is out of stock.

We have products that need to show in the products listing, even if zero stock. Therefore, we cannot turn that off.

Is there anyway to just hide it on the product options page? Or better yet, change the options in the dropdown from "yes/no" to "out of stock" if quantity=0 for that particular product option?
