self explanatory but it's nice to keep a field hidden unless it's needed. For instance if you want to show field a field such as "are you pregnant" but only to females, you would make the 2nd field conditional on if they checked "female".
In the field area you would have a dropdown to show all radio and checkbox fields. When you select one of these fields, the options for that field are shown. You then check the values that will show the new field. In my example:
{eb_sex}
- [male]
+ [female] <- show my new field
