Problems with django-smart-select

[thejpanganiban]

Additional class=chained-fk and data-* attributes from the widget ChainedSelect (https://github.com/jazzband/django-smart-selects/blob/master/smart_selects/widgets.py#L54) does not render. They're needed attributes so bindfields.js would work properly.

Tried @Thutmose3's branch (#163) as well, with no luck.

Here's what I understand so far:

1. ChainedSelect widget generates attributes (class=chained-fk, and some data-attributes) that's later picked-up by the jQuery functions of django-smart-select.
2. Widget attributes for some reason does not render in the template when using django-crispy-forms + tailwind.
3. Found out that attributes are generated differently on <select>: field|build_attrs vs {% include "tailwind/layout/attrs.html" ... %}.
4. Replaced tailwind/layout/select.html so that it uses Django's original template (plus some modifications so that variables match), and additional attributes are still not rendering.

Where could the attributes from ChainedSelect have gone?
