How to reset all slots in a Form

After completing the form filling , I want to fill the same form with new values. then How to reset all slots in a Form.

You can reset the slots in the submit function of the form. The submit function is called when the form is completed. If your form has, for example, the following requested slots, ["cuisine", "num_people", "outdoor_seating"], you can, for example, reset the slots by doing

    def submit(
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any],
    ) -> List[Dict]:
        """Define what the form has to do
            after all required slots are filled"""

        # utter submit template
        dispatcher.utter_template("utter_submit", tracker)

        return [
            SlotSet("cuisine", None),
            SlotSet("num_people", None),
            SlotSet("outdoor_seating", None)

Does this help?
