<!--website/add.html -->
<form action="" method="post">
<div>
{{ website_form }}
</div>
<div>
{{ section_formset }}
</div>
<input type="submit" value="submit">

After submitting the form for the first time and inserting some data, I visit the same URL for inserting more data. But the form of section formset is pre-populated with the data inserted the previous time.
