Hello. Is there a way to pop up a field only when a particular value of its "parent field" has been selected ? For example, a Multi Select Box displays engineering fields (software, mechanics, electronics, etc.), when I select one of them another Multi Select Box should appear in order to select other values (e.g. development, testing, etc.). I looked at the Field dependencies, but there the fields as "children" are always there, and if you set Required, you must select a value even if not dependent from the "parent".
