Formset is a way to render multiple forms in one page, like a grid of data. Ex: This ChoiceForm might be associated with some question of sort. like, Kids are most Intelligent between which age?.

appname/forms.py

from django import forms
class ChoiceForm(forms.Form):
    choice = forms.CharField()
    pub_date = forms.DateField()

In your views you can use formset_factory constructor which takes takes Form as a parameter its ChoiceForm in this case and extra which describes how many extra forms other than initialized form/forms needs to be rendered, and you can loop over the formset object just like any other iterable.

If the formset is not initialized with data it prints the number of forms equal to extra + 1 and if the formset is initialized it prints initialized + extra where extra number of empty forms other than initialized ones.

appname/views.py

import datetime
from django.forms import formset_factory
from appname.forms import ChoiceForm
    ChoiceFormSet = formset_factory(ChoiceForm, extra=2)
    formset = ChoiceFormSet(initial=[
      {'choice': 'Between 5-15 ?',
        'pub_date': datetime.date.today(),}
      ])

if you loop over formset object like this for form in formset: print(form.as_table())

Output in rendered template

<tr>
<th><label for="id_form-0-choice">Choice:</label></th>
<td><input type="text" name="form-0-choice" value="Between 5-15 ?" id="id_form-0-choice" /></td>
</tr>
<tr>
<th><label for="id_form-0-pub_date">Pub date:</label></th>
<td><input type="text" name="form-0-pub_date" value="2008-05-12" id="id_form-0-pub_date" /></td>
</tr>
<tr>
<th><label for="id_form-1-choice">Choice:</label></th>
<td><input type="text" name="form-1-choice" id="id_form-1-choice" /></td>

<tr>

<td><input type="text" name="form-1-pub_date" id="id_form-1-pub_date" /></td

<tr>
<th><label for="id_form-2-choice">Choice:</label></th>
<td><input type="text" name="form-2-choice" id="id_form-2-choice" /></td>
