from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Div, Field

from django import forms

class MyForm(forms.Form):
    field1 = forms.CharField()
    field2 = forms.CharField()
    condition = forms.BooleanField(required=False)

class MyForm(forms.Form):
    field1 = forms.CharField()
    field2 = forms.CharField()
    condition = forms.BooleanField(required=False)

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.layout = Layout(
            Div(
                Field('field1'),
                Field('field2'),
                css_class='normal-fields'
            ),
            Div(
                Field('condition'),
                css_class='conditional-fields'
            )
        )

{% load crispy_forms_tags %}
<form method="post">
    {% csrf_token %}
    {% crispy form %}
    <button type="submit">Submit</button>
