Hi,
Thank you for these explanations. I am still discovering some parts of VM2.
Currently with version 2.0.6, I could not find how to have the custom fields in drop down menu translated.
I have made a template override of default_customfields.php, adding JTEXT when missing. The CONSTANT is translated, but not the VALUE.
Then in the cart, VALUE is OK.
Electrocity, please, which files did you modify to get it working properly?
