I have a check box acting as the dependee. When it is checked, it opens up a free-tagging term-reference field. So when
A is checked,
B appears and users can add tags:
A (checkbox): 
B (tags): [________]
In the settings I have the following selected:
"Reset the dependent to its default values when the form is submitted if the dependency is not triggered."
The default value for the term-ref field is blank. When the checkbox (dependee) is unchecked and the content saved, it should revert to the default value. However, all added terms remain.
Is there a way to remove all taxonomy terms in this scenario? I have multiple dependee/dependent fields in the content type, so it would have to act independently of other fields.
