Introduction
============
plone.formwidget.contenttree is a z3c.form widget for use with Plone. It
uses the jQuery Autocomplete widget, and has graceful fallback for non-
Javascript browsers.
There is a single-select version (AutocompleteSelectionFieldWidget) for
Choice fields, and a multi-select one (AutocompleteMultiSelectionFieldWidget)
for collection fields (e.g. List, Tuple) with a value_type of Choice.
When using this widget, the vocabulary/source has to provide the IQuerySource
interface from z3c.formwidget.query and have a search() method.
Example Usage::
from zope.component import adapts
from zope.interface import Interface, implements
from zope import schema
from plone.z3cform import layout

class ITestForm(Interface):
buddy = schema.Choice(title=u"Buddy object",
description=u"Select one, please",
source=PathSourceBinder(portal_type='Document'))
friends = schema.List(
title=u"Friend objects",
description=u"Select as many as you want",
value_type=schema.Choice(
