Multiple Form Submit with Single Submit Button

I'm currently working with django project. I had to filter the data store on the database based on the user input on form (at template) as looked below. On form user either enter value or

pass variable value store in dictionary to url parameter

I pass dict addon_id_value_mapping = {'menu': '1', 'opening_hour': '2', 'books': '3', 'doctors': '4'} and addon_list = [{u'menu': [{u'price': 50, u'name': u'Momo', u'price_level': u'cheap'}, {u'price': 510, u'name': u'potato', u'price_level': u'expensive'},
