I was reading this issue: http://drupal.org/node/1705126 and it is very close to what I need to achieve, with exception that I'm uing custom fields that are provided by other modules. (e.g. "Select or Other", "Webform Accordion")

This is a great module, yet it limits the possibilities of my web forms by supporting only out of the box fields.
I'd also appreciate if someone could point me to a work around on how I can implement above field modules without disabling Form Builder.
