How can I add a (help/info) button that opens a new small window in the checkout shipping process (checkout_shipping module)???
I need that resembles the help button of the shopping cart to put characteristic of each shipping method and I find it the best form for it.
I don't know anything of php , I tried to imitate the way in that the button helps works in the shopping cart module but it didn't work me although I changed the code.
Thank you for help.
