I was just wondering whether Payment Form is a responsive module?
I have got the module installed in my website, but it does not seem to resize properly in mobile devices. Is this a built-in feature or something that needs to be modified to re-scale properly in mobile devices? I'm using Joomla 3.x.
Payment Form has different layouts to display form and at the moment, only bootstrap layout is responsive. So when you create the form, in the Form layout parameter, please enter bootstrap and it should work well.
