Module to hide inactive attributes in dropdown menus

[stavrosvorkas]

Hello, I am looking for a module that offers me the ability to have combinations that don't exist greyed out in the drop down menu.

 

Example. Protein powder A : 3 different sizes (200g 500g 1kg) and many flavours (strawberry kiwi bannana orange etc etc).

 

where it gets tricky, orange in 200g does not exist so I would like it to be greyed out or with a strike through line  when I click the flavours drop down.

 

I have found a plugin that changes the layout of the product page which is something I don't want. I want to be able to sustain my two drop down menus look (less is more IMO)

 

many thanks:)
