One parent product with several stockable child products in product view only?

[JJBW]

Hi all

Can you now have one parent product in the category layout with several stockable child products in the product details only?

For example like this:

http://www.sportsdirect.com/karrimor-long-sleeve-zip-tech-t-shirt-mens-444150?colcode=44415092

When you select a different colour from the colour dropdown box the image changes accordingly and will inform you if it's out of stock or not.

Is this possible please?  Quite desparate to get this working!!

Many thanks for your time.
