Add missing css_class to accordion and accordion-group templates

[kosdmit]

This PR is based on PR #169, and it completely resolves issue #168 .

I've fixed accordion.html and accordion-group.html templates and written a few tests for checking css_classes is rendered correctly. I've also fix some tests templates, because the first accordion item should have css_class 'active' by default (look comment in issue for details.

Thanks for the PR!

Just one comment on about this:

because the first accordion item should have css_class 'active' by default

Is this the case with Bootstrap 5? I can't see any reference to this class in their docs and trying it locally seems to indicate there are no styles for that class?

You are right, that is my mistake, bootstrap 5 does not use 'active' class. But we have probably a legacy method in django-crispy-forms which adds 'active' to css_class string:

class Container(Div):
    def render(self, form, context, template_pack=TEMPLATE_PACK, **kwargs):
        if self.active:
            if "active" not in self.css_class:
                self.css_class += " active"
        else:
            self.css_class = self.css_class.replace("active", "")
        return super().render(form, context, template_pack)

I think it's would right to add a separate attr to define activity of item, and do not add this class to css_class string. What do you think?

I was wondering where this was actually required, seems that it is for tabs rather than accordion.

Maybe we should move render() method you provided above to Tab from Container? I can't see active being on an accordion going back to Bootstrap 3, see docs but would need to do some further testing of that.

Hi @smithdc1,

I've done some work to close that issue in this template pack:

• Reverted incorrect changes in test result's templates. They don't use 'active' class as per the bootstrap docs.
• The tests that were failing by the django-crispy-form reason, get compatible with current lib versions parameter. It also marked as xfail with condition specified by crispy_forms version.

Could you add an entry to the changelog?
