What is happening?

When trying to use Form groups, I get the following error:

AttributeError: module 'dash_bootstrap_components' has no attribute 'FormGroup'

What should be happening?

Deprecation warning if FormGroup will be removed

Hi @xhlulu

I agree it would have been better to have a deprecation warning for FormGroup and the other breaking changes in V1. However, this new version uses Bootstrap V5 --and FormGroup, along with several other components -- were dropped by Bootstrap in V5: https://getbootstrap.com/docs/5.1/migration/#forms

There are lots of cool new features in dash-bootstrap-components v1.0, so hopefully it will be worth the effort to upgrade existing apps.

See more info in the migration guide

I think we should put in a more informative error if the user tries to use FormGroup, directing them to the above migration guide etc. and informing them that this has happened because they're using v1. There will be people who inadvertently upgrade just because they do a clean install or something and might be confused about why their app suddenly stopped working.

Good idea - and include not only FormGroup but all the dropped components -- and props. There should also be a an alert on the current version of the docs directing people to the new docs if they are using V1

Added deprecation warnings in the second beta

pip install -U --pre dash-bootstrap-components
