I would like to know how I can change the field type of a customized input field in the magento backend.
I'm talking about this screen: Customer => Manage Customers => Account Information
Usually there is a .phtml file to configure your fieldtype but for this specific screen i couldn't find any!
In case of the Customer View I was able to find a .phtml file in the following folder:
C:\xampp\htdocs\magento\app\design\adminhtml\default\default\template\customer\tab
But as I said, there isn't any for the Account Information screen. Did I miss something?
I'd like to change the type from 'input type="text"' to 'textarea' in the frontend it worked like charm, but in the backend?
Please help!
