Widgets

A form widget is available for displaying radio buttons as a Bootstrap 4 button group(https://getbootstrap.com/docs/4.5/components/button-group/).

RadioSelectButtonGroup

This renders a form ChoiceField as a Bootstrap 4 button group in the primary Bootstrap 4 color.

from bootstrap4.widgets import RadioSelectButtonGroup

class MyForm(forms.Form):
    media_type = forms.ChoiceField(
        help_text="Select the order type.",
        required=True,
        label="Order Type:",
        widget=RadioSelectButtonGroup,
        choices=((1, 'Vinyl'), (2, 'Compact Disc')),
        initial=1,
    )
