Hi,
I am Opencart expert. So you need the existing form to modify like the Doc and in 3 languages, En, De, Fr?
Can you tell me how you created the existing form and is it managed from Admin or just a hardcoded form?
I dont understand the language in the form, so I assume there is no functionality changes in Form and both existing and new doc form is same, only the layout will change.
Thanks
Harsh
