Regarding the selection of the first child variant on the dropdown

[davicod]

Regarding the problem to select the first product variation of the dropdown list on the product details page, i followed the instructions descripted at
https://forum.virtuemart.net/index.php?topic=110203.msg410620#msg410620
It worked fine except that when i select any of the variation, the text --Please Select-- is clickable and returns the parent product.
Does anyone has a solution for this?

Also if there is any alternative solution (like a list of variations instead of the dropdown) it will be suitable for me.
And by the way, anyone knows any extention that adds a better functionality to this feature?

I m working with joomla 2.5.20 and VM 2.6.6.

Thanks for your time
