Django crispy forms work with custom widgets?

Question

Following the code in this post, I was able to group the options in a ModelMultipleChoiceField based on another field. As described in this post, I used a custom widget (literally the one that is in the post):

Grouping CheckboxSelectMultiple Options in Django

so now the form is rendering the way I'd like it to, but I was hoping to improve on the formatting by using crispy forms. however, when I added {% load crispy_forms_tags %} and {{form|crispy}} it rendered the form without the grouping that I worked so hard to achieve...

does anyone know how if its possible to apply crispy forms to a form with a custom widget and preserve what the widget does?

thanks!

No, this won't be possible because crispy forms never calls the render method of the widget.

An alternative is to override the template for the widget, in this case bootstrap/layout/checkboxselectmultiple.html, to use the grouping as required.
