Creating sub-fields within a field I am using the profile2 module in Drupal 7. I have created a field using the check box/radio widget that has 2 options and both options can be checked. How would I be able to create a sub-field that will show another checkbox/radio widget with options depending on what was checked in the main field?
For Drupal 6, there was Conditional Fields.

There is no Drupal 7 version yet, but there is an issue which links to field conditional state which at this point is only a sandbox project but seems to be widely used already.
