Create your DynamicFormClass and add static fields

If you need some static field in your form, than you can define a new Form Class, inheriting BaseDynamicForm

from django_form_builder import dynamic_fields
from django_form_builder.forms import BaseDynamicForm

class MyDynamicForm(BaseDynamicForm):
    def __init__(self,
                 constructor_dict={},
                 custom_params={},
                 *args,
                 **kwargs):
       # Add a custom static field common to all dynamic forms
       self.fields = {}
       my_static_field = dynamic_fields.format_field_name(choice_field_name)
       my_static_field_data = {'required' : True,
                               'label': choice_field_label,
                               'help_text': choice_field_helptext}
       my_static_field = getattr(dynamic_fields,
                                'CustomFieldClass')(**my_static_field_data)
       self.fields[my_static_field_id] = my_static_field

       # call super() constructor to build form
       super().__init__(# define it only if you
                        # define a custom field source,
                        # see "Create your own fields" paragraph.
                        # fields_source=dynamic_fields_integration,
                        initial_fields=self.fields,
                        constructor_dict=constructor_dict,
                        custom_params=custom_params,
                        *args, **kwargs)

    # if needed, override clean() method with your own params
    def clean(self, *args, **kwargs):
        cleaned_data = super().clean(own_param=own_value)
