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
