A ``GroupedChoice`` field takes the\nexactly same parameters as the stock ``Choice`` field but additionally\nan instance of a groups provider (implementing\n``horae.groupedselect.interfaces.IGroups``) has to be provided over the\nparameter ``groups``. The mentioned groups provider converts the\nvocabulary of the field into a list of groups.\n\nImagine field to select a country and you would like to group them by\nregion::\n\n    from zope import interface, implements\n    from zope.schema import vocabulary\n    \n    from horae.groupedselect import field, interfaces\n    \n    class Country(object):\n        def __init__(self, region, country):\n            self.region = region\n            self.country = country\n    \n    class CountryGroups(object):\n        implements(interfaces.IGroups)\n    \n        def groups(self, vocabulary):\n            \"\"\"\n            Converts the given vocabulary into a list of groups:\n    \n                return (('Group 1', (term1, term2, term3)),\n                        ('Group 2', (term6, term5, term6)),)\n            \"\"\"\n            groups = {}\n            for term in vocabulary:\n                if not term.value.region in groups:\n                    groups[term.value.region] = ()\n                groups[term.value.region] = groups[term.value.region] + \\\n                    (term,)\n            return groups.items()\n    \n    class ICountrySelection(interface.Interface):\n        \n        country = field.GroupedChoice(\n            title = u'Country',\n            vocabulary = vocabulary.SimpleVocabulary((\n                # ...\n                vocabulary.SimpleTerm(\n                    Country(u'Europe', u'Switzerland'),\n                    'ch',\n                    u'Switzerland'\n                ),\n                vocabulary.SimpleTerm(\n                    Country(u'Europe', u'Germany'),\n                    'de',\n                    u'Germany'\n                ),\n                vocabulary.SimpleTerm(\n                    Country(u'Europe', u'Austria'),\n                    'at',\n                    u'Austria'\n                ),\n                vocabulary.SimpleTerm(\n                    Country(u'Europe', u'France'),\n                    'fr',\n                    u'France'\n                ),\n                # ...\n                vocabulary.SimpleTerm(\n                    Country(u'North America', u'USA'),\n                    'us',\n                    u'USA'\n                ),\n                vocabulary.SimpleTerm(\n                    Country(u'Europe', u'Canada'),\n                    'ca',\n                    u'Canada'\n                ),\n                # ...\n            )),\n            groups = CountryGroups()\n        )\n\nDependencies\n============\n\n* `zope.schema <http://pypi.python.org/pypi/zope.schema>`_\n* `zope.formlib <http://pypi.python.org/pypi/zope.formlib>`_\n\nChangelog\n=========\n\n1.0a1 (2012-01-16)\n------------------\n\n* Initial release",
