My form field is :
class CityForm(forms.ModelForm):
class Meta:
model = City
fields = ['city1', 'city2', 'city3', 'city4', 'city5', 'userName']
widgets = {
'city1': autocomplete.Select2(url='city-autocomplete'),
'city2': autocomplete.Select2(url='city-autocomplete'),
'city3': autocomplete.Select2(url='city-autocomplete'),
'city4': autocomplete.Select2(url='city-autocomplete'),
'city5': autocomplete.Select2(url='city-autocomplete'),
}
