Multi language fields for Plone

Project Description



This package is still in a public experimentation phase.

This package aims to provide a simple way to make some fields on a dexterity content type available in more than one language (“multilanguage”). It tries to do what raptus.multilanguagefields does for Archetypes content types.


  • It should be possible for a site to add a new supported language without having to migrate content. (A modification in the code for your customer-specific package would be ok.)


Multilanguage text line:

from collective.multilanguagefields.fields import TextLine as MLTextLine
from plone.supermodel import model

class IMyType(model.Schema):

    some_text = MLTextLine(



Plone 4.3 and upwards.

Making Title field multilanguage

You cant use the default behavior. Instead, use collective.multilanguagefields.interfaces.INameFromMultiLanguageTitle

In addition, your content type needs to implement its own Title() method which takes into account that the title attribute contains a dictionary. The ml_value method from might be helpful.

Using multilanguage fields in templates

You can do this as follows:

<span tal:content="context/ml_value/my_field" />

You can also specify a default value:

<span tal:define="ml_value context/ml_value"
      tal:content="python: ml_value('my_field', 'no translation found')" />
