+ *   An array of elements to make invisibile in the form, each element in turn being
+ *   an array of form keys corresponding to the path of the element in the form
+ *   structure. For example, to hide the element $form['comment_filter']['format']

+ * @param $inverse

+ *   invisible. This defaults to FALSE.
