These widgets perform sorting on the choices within Python.
This is useful when sorting is hard to due translated fields, for example:

* the ORM can't sort it.
* the ordering depends on ``gettext()`` output.
* the model ``__unicode__()`` value depends on translated fields.

Use them like any regular form widget::

    from django import forms
    from parler.widgets import SortedSelect

    class MyModelForm(forms.ModelForm):
        class Meta:
            # Make sure translated choices are sorted.
            model = MyModel
            widgets = {
                'preferred_language': SortedSelect,
                'country': SortedSelect,
            }
