OK, so first of all thanks for all the great work done on this. I was starting to write a whole cart and ordering app from scratch...
I have been asked to update a pizza shop to provide online ordering.
It is running on joomla1.5 so I'll probably want to stick to that to not complexify my life further

Now, I am creating pizzas as products.
We need to provide the user the possibility to choose additional ingredients.
So I created custom fields, and instinctively created them as boolean type.
However, when I look at my pizza, the options appear fine, but there is only one radio saying "Yes" and it is preselected.
I can't see no way to deselect the option.
I need to be able for the user to select/deselect the ingredient / custom field.
How to do that? Is that a bug for the boolean custom field, or should I use something else?
thanks
