Interdependent shopper fields

[EvanGR]

Hello,

I want to create interdependent shopper fields for the checkout form. So that e.g. depending on the selection on field A, fields B and C get enabled or disabled.

Is this possible to do with VM alone?

If not, I could add some custom javascript to handle that. I am not sure if that would be straightforward enough (i.e. if the HTML output from VM would make it easy to find and manipulate the relevant fields)

I would like to avoid commercial extensions for this simple purpose. Any ideas?

Thanks
