Add Better Exposed Filters support

Solved, I've opened a Merge Request. There is a failure in the pipeline regarding phpUnit which doesn't seem to be anything related to the changes.

Attaching file patch as well.

Previous attached file patch was wrong because the MR was created to branch 3.0.x by default.

LGTM

I understand that this is an integration, and we would not like to put this in the main javascript file.

However there is no guarantee that this script will run after the "chosen" library already applied itself.

Instead of relying on document ready calls in a behavior which can be called by Drupal several times on a page, it would be better to somehow guarantee that the code runs after the chosen library ran, and that this script is using the "once" function instead of document ready.

This patch might be more robust.

Automatically closed - issue fixed for 2 weeks with no activity.
