An optgroup widget for z3c.form.
Project description
Introduction
This package implements a widget that groups select values into optgroups.
Usage
Imagine you have the following schema:
class IMySchema(Interface): country = schema.Choice( required=True, title=u"Country", vocabulary='countries', ) subdivision = schema.Choice( required=True, title=u"State", vocabulary='subdivisions', ) region = schema.Choice( required=True, title=u"County", vocabulary='regions', )
When you create your vocabularies (e.g. using SimpleVocabulary), instead of adding SimpleTerm items:
... for country in pycountry.countries: terms.append(SimpleTerm(value=country.alpha2, token=country.alpha2, title=country.name)) ...
you add OptgroupTerm items:
from z3c.formwidget.optgroup.widget import OptgroupTerm ... country_list = countries(context) for item in pycountry.subdivisions: parent = country_list.getTermByToken(item.country_code).title terms.append(OptgroupTerm(value=item.code, token=item.code, title=item.name, optgroup=parent)) ...
In your form, simply assign the OptgroupFieldWidget:
from z3c.formwidget.optgroup.widget import OptgroupFieldWidget class MyForm(form.Form): fields = field.Fields(IMySchema) fields['subdivision'].widgetFactory = OptgroupFieldWidget fields['region'].widgetFactory = OptgroupFieldWidget
