I'm trying to use ModelAdmin.filter_horizontal and ModelAdmin.filter_vertical for ManyToMany field instead of select multiple box but all I get is:
My model:
class Title(models.Model):
#...
production_companies = models.ManyToManyField(Company, verbose_name="????????-?????????????")
#...
My admin:
class TitleAdmin(admin.ModelAdmin):
prepopulated_fields = {"slug": ("original_name",)}
filter_horizontal = ("production_companies",)
radio_fields = {"state": admin.HORIZONTAL}
#...
The javascripts are loading OK, I really don't get what happens. Django 1.1.1 stable.
