Variations and Swatches – Woocommerce – Dropdown Groups

Hi Guys

We need the variable products to have the option to work like here: http://www.nest.co.uk/product/muuto-rest-three-seater-sofa
Using the dropdown if you select any of the three options you are presented with different groups of swatches. We need this same function. Eg. dropdown containing: option 1, option 2, option 3 – each option when selected shows a different group of swatches:
OPTION 1
red swatch – green swatch – yellow swatch
OPTION 2
black swatch – white swatch
OPTION 3
blue swatch – pink swatch – orange swatch
Just like: http://www.nest.co.uk/product/muuto-rest-three-seater-sofa
In the back of the wordpress site each swatch must be associated with a attribute, therefore being able to assign stock to each.

Anyone know a plugin that can support this? Can Variation Swatches and Photos?
