Hello,
I'm not sure if this is possible. There is a section property that you can use to disable a section when in card layout. initDisabled is what you would want to modify. Lets say you have a survey with two sections each containing some questions. In section 2 you can attach a listener to one of your questions that listens for changes from a question in section 1. So having questions affect other questions across sections is possible but I'm not sure if you could attach a listener to section that listens for change from a question. You should try and play around with that initDisabled property, and I can see if the devs have any suggestions.
Thanks,
Chet
