I just remembered that AS has a popup mode for add_new, which worked
exactly as I described, so I have added support for add_new with popup mode
in multiple associations.
You can use form_ui = :chosen, {add_new: {mode: :popup}}, or you can use
the short syntax, form_ui = :chosen, {add_new: true}, which will default to
popup mode for multiple associations.
It's supported for :select and :record_select on multiple associations too,
for any of the :select versions on collection associations (checkboxes,
draggable lists or select tag with multiple attribute).
Regards,
Sergio
