I have seen many different plugins and ways to configure Magento product variations, but I wasn't able to find a way to do the following out of the box or using some plugin (doesn't matter if its free or paid):
Have a look at the following Amazon URL: http://www.amazon.ca/Seagate-Expansion-Desktop-External-STBV2000100/dp/B00834SJS0/
I would like when I select one of the options to go to the product variation selected (instead via AJAX like in the Amazon case, but same concept).
I would also like all the product variations listed in the store and search and have the ability to choose another variation from every other option: For example im in the 1 gig product, I will still see 2gig and 4gig with ability to switch and vice-versa.
Lastly I would like to hide the "base" product from everywhere, so I also have the final options displaying in the store, the base product can still be present in the backend as a pivot, but should be hidden from everywhere else.
Do you have a clue if there is something that does that out of the box or with very little modifications?
Good news for you :)
Look at this free module: Easylife_Switcher
https://github.com/tzyganu/Switcher
It also supports graying out options not in stock.
