I am quite a new user to Magento. Currently using 1.9.2.1 with 3rd party theme.
I am setting up configurable products. I see on the shop side any combination not available still shows up as a drop down option but is "greyed out" so it cant be selected. Is this a new thing?
I am sure an older version I used a while back any combination not available just didnt show on the drop downs. Also the Youtube vids I have watched about setting up configurables shows it so when something is not an available option it doesnt show.
It has been driving me mad as I am sure it used to do this. Either Magento has changed standard behaviour or I have changed an option setting somewhere and cant find how to change it back!
I even installed a default store on a spare domain just to check how it works "out the box"
Can anyone shed some light on this please!! Thank you
