In both the above images, the size

(Twin XL,Twin, Full, etc)

is selected and the above size of the product changes dynamically as (39x80x12),(54x75x12).

I tried to make changes in the configurable.php, wrapper.phtml, renderer.phtml and also in the configurable.js but I couldn't get a solution for this. Is theres a way to make it possible to display the size dynamically based on the drop down of size?
