19755	Incremental filter	paulox@…	Przemysław Suliga	"Would be a good feature to have filter's value that change incrementally when user select one of them.


I try to explain with an example:


{{{
class Person(models.Model):
    name = models.CharField()
    hair_color = models.CharField()
    eye_color = models.CharField()

class PersonAdmin(admin.ModelAdmin):
    list_filter = [""hair_color"", ""eye_color""]
}}}

At first I'll see all hair color and eye color values in the filter.

When I select an hair color value from the filter I'll see only person with that hair color.

I would view in the eye color filter only distinct values of eye colors of person that have hair color I selected from the filter."	New feature	assigned	contrib.admin	dev	Normal		filter, admin	suligap@… Collin Anderson	Design decision needed	1	0	0	1	0	1
