I want to display the option of Add to Cart on the Category page itself, like in the following website:
http://market.bart-ingredients.co.uk/
Also, is it possible to have the product view page in the same format as in the website: http://market.bart-ingredients.co.uk/
There is topic which solves this problem at http://forum.virtuemart.net/index.php?topic=90961.0 (http://forum.virtuemart.net/index.php?topic=90961.0)
And for the product page, you can style & lay it out however you want using template/css overrides.
