Life, the Universe, and Everything

A widget package for Dexterity projects.

collective.z3cform.widgets provides the following widgets:

EnhancedTextLinesFieldWidget

This widget is an ajaxified version of the TextLinesFieldWidget that will allow creation, sort, update and deletion of text lines; degrades to <textarea> if JavaScript is not enabled.

This widget uses the jQuery TaskPlease plugin.

TokenInputFieldWidget

TokenInputFieldWidget allows your users to select multiple items from a predefined list, using autocompletion as they type to find each item. You may have seen a similar type of text entry when filling in the recipients field sending messages on Facebook. This widget will degrade to <textarea> if JavaScript is not enabled.

This widget uses the jQuery Tokeninput plugin.

If you install collective.z3cform.widgets in a Plone site it will replace every ICategorization subjects field’s widget of any Dexterity-based content type with this one.

MultiContentSearchFieldWidget

A widget to add a dynamic list of objects. This works as a widget for related items field so it must be used like this:

relatedItems = RelationList(
    title=_(u'label_related_items', default=u'Related Items'),
    default=[],
    value_type=RelationChoice(title=u"Related",
                  source=ObjPathSourceBinder(portal_type='Document')),
    required=False,
    )
form.widget(relatedItems=MultiContentSearchFieldWidget)

The parameters passed to the ObjPathSourceBinder class are used to filter the search of elements to relate to. If no parameters are passed, a tree structure is shown in the widget.

SimpleRichTextWidget

A lightweight and unbloated Rich Text Editor (RTE / WYSIWYG). These parameters can be configured:

'iframe_height': height in pixels,
'format_block': 'true' or 'false',
'bold': 'true' or 'false',
'italic': 'true' or 'false',
'unordered_list': 'true' or 'false',
'link': 'true' or 'false',
'image': 'true' or 'false',
'allow_disable': 'true' or 'false'

This widget uses the jQuery RTE plugin.
