Volto features the Pastanaga Editor Engine, allowing you to visually compose a page using blocks. The editor allows you to add, modify, reorder and delete blocks given your requirements. Blocks provide the user the ability to display content in an specific way, although they can also define behavior and have specific features. Blocks are composed of two basic (and required) components: the Block edit and view components.

By default, Volto ships with the most basic set of Blocks: Title, Text, Image, Video, Maps, etc...


Volto Blocks are not enabled by default in Plone content types. The interface for this behavior is plone.restapi.behaviors.IBlocks. If you are using the kitconcept.voltodemo package, it sets it up for you for the Document content type.

How to manually enable Blocks on a content type#

You can enable them on any content type by enabling Blocks behavior provided by plone.restapi.

  1. Go to ControlPanel -> Dexterity Content Types, select the content type.
  2. Go to Behaviors
  3. Select the Blocks behavior
  4. Save

You can also add the behavior programatically via GenericSetup:

<?xml version="1.0"?>
<object name="LRF" meta_type="Dexterity FTI" i18n:domain="plone"
 <property name="behaviors" purge="false">
  <element value="plone.restapi.behaviors.IBlocks" />

Test that the content type you've just enabled Blocks behavior is working, by creating a new object of that type from Volto.
