I have the same issue. the first empty label has been changed to ' Select Cateogory' from the django default '------' .

But on the second select field (i.e the ChainedForeignKey in the model) , the empty_label is still showing the django default '----'

Please assists !!!

self.fields['category'].empty_label = 'SELECT CATEGORY' <--- works
self.fields['subcategory'].empty_label = 'SELECT CATEGORY' <--- Does not work

any solutions to this?

Check the foreign key models.py for the absence of "to-field = yourchoose,".
Smart-selects only works with a pointer:
/ chaining / filter / app / model / field / field_id / fieldwhereyoucreate / field / yourvalue /
yourvalue = id of the parent subcategory.
It took me 3 hours to figure it out.
It would be nice to add all (part) your models.py code here.
