from django import forms
from django.forms import formset_factory

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = '__all__'
        widgets = {
            'can_delete': forms.HiddenInput(),
        }

MyFormSet = formset_factory(MyForm)

def my_view(request):
    formset = MyFormSet()
    return render(request, 'my_template.html', {'formset': formset})

<!-- my_template.html -->
<form method="post">
    {% csrf_token %}
    {{ formset.management_form }}
    {% for form in formset %}
        {{ form }}
    {% endfor %}
    <input type="submit" value="Submit">
</form>
