    ...Compatibilityplone.volto currently works for both Plone 5.2 and Plone 6 (pre-alpha and alpha).
It support Python 3.7, 3.8 and 3.9.Though, Volto requires specific versions of plone.volto and plone.restapi:plone.voltoplone.restapiReason3.1.x8.13.0 and aboveRequires new JSONSummarySerializerMetadata serializer added in plone.restapi 8.13.02.x (kitconcept.volto)7.0.0 and aboveNew image scales1.x (kitconcept.volto)6.0.0 and belowNew transforms and featuresplone.restapi 7.x.x is included in Plone 5.2.4 (and later).You can still use 2.x in p.restapi 7.0.0 based installations but the transforms included won’t work.Volto only supports the latest plone.restapi branch, therefore it is recommended to always use the latest version in your Volto projects.Plone 6 architectureArchitectural Diagram of Plone 6:Frontend

└──────────────────────────────┘Featuresplone.volto provides the following features:Volto blocks supportplone.volto enables the new Volto Blocks editor onDocument,Language Root FolderandSite Root.Block types indexplone.volto adds ablock_typesindex to the Plone catalog.
It can be used to query for items that use a particular type of block.fromploneimportapiportal_catalog=api.portal.get_tool("portal_catalog")portal_catalog.searchResults(block_types="image")Theblock_typesindex was added in plone.volto 4.1.0.
By default it is only added for new Plone sites.
To add it to an existing site, runplone.volto.upgrades.add_block_types_indexmanually.Multilingual supportplone.volto supports multilingual websites.
Install PAM before installing this package and demo homepages will be created in each enabled language.
Currently only support for EN/DE.Volto blocks for Plone site rootplone.volto contains a hack to make the Plone site Volto blocks-enabled with some demo content.
You can take only the hack to enable the blocks on your site.You can see it in action in the Volto demo:https://6.demo.plone.orgInstall the provided profile to install it by default:plone.volto:default-homepagee.g. in your GSmetadata.xmlalong with your other dependencies:<metadata>
<version>1000</version>
<dependencies>
  <dependency>plone.volto:default-homepage</dependency>
</dependencies>
</metadata>NOTE: The default block for creating the default content in the root (or
corresponding Language Root Folders) is “draftJS” text block.plone.voltoprovides a
profile if you want to create Slate blocks: you need to use thedefault-homepage-slateprofile.Document content typeplone.volto disables theRichtextandTable of Contentsbehaviors for theDocumentcontent type.
Rich Text functionality is provided by the new Volto Blocks editor.
TheTable of Contentsfunctionality is provided by theTable of Contents Blockin Volto.CORS profileA quick helper for enable CORS for development config is also provided in theplone.voltomodule. So you can call:<include package="plone.volto.cors" />from your ZCML while developing.Enable it on demand, since it’s considered a security issue if you enable CORS in your
productions sites.It’s planned that Volto will feature a development pass-through proxy to the backend in
the future. It will be addressed in next sprints.ZLog patchp.restapi low level errors are routed through the ancient ZLog and areplone_errorenabled, making it difficult to follow since all are marked with a UUID. Specially if
using helpers like Sentry. This patch removes the UUID so the same error is categorized
all together. This is planned to be addressed in next sprints.Patch forsubjectfieldThere are some problems of serialization on special characters derivated from how the
current shape of the Plone’s default Dexteritysubjectsfield that has to be
addressed in order to make it work properly with Volto (and other systems that are not
Plone). This will be fixed in core in upcoming sprints.Preview image behaviorThe preview image behavior makes content types provide apreview_imagefield that can store a preview image that Volto views can pick up.
This is especially userful for listings (e.g. listing block customizations) and teaser elements (e.g. teaser blocks such as [volto-blocks-grid](https://github.com/kitconcept/volto-blocks-grid)).Thevolto.preview_imagebehavior can be enabled in the generic setup XML definition of a content type (e.g./profiles/default/types/MyContentType.xml):<?xml version="1.0" encoding="UTF-8" ?>
<object i18n:domain="my.project" meta_type="Dexterity FTI" name="MyContentType"
  xmlns:i18n="http://xml.zope.org/namespaces/i18n">

  ...

  <!-- Enabled behaviors -->
  <property name="behaviors" purge="false">
    ...
    <element value="volto.preview_image" />
  </property>
  ...
</object>There is also another variation of the preview image behavior calledvolto.preview_image_link.
This one stores preview images using a relation to an Image content type, rather than in an image field. This might be preferable if many content items use the same preview image.Navigation title behaviorThe navigation title makes content types provide a nav_title field that is used by Volto in the main navigation, the breadcrumbs and the navigation portlet.The “volto.navtitle behavior can be enabled in the generic setup XML definition of a content type (e.g. “/profiles/default/types/MyContentType.xml”):<?xml version="1.0" encoding="UTF-8" ?>
<object i18n:domain="fzj.internet" meta_type="Dexterity FTI" name="MyContentType"
  xmlns:i18n="http://xml.zope.org/namespaces/i18n">

  ...

  <!-- Enabled behaviors -->
  <property name="behaviors" purge="false">
    ...
    <element value="volto.navtitle" />
  </property>
  ...
</object>Head title behaviorThe headtitle makes content types provide a headtitle field that can be used by Volto in teasers and alikes.The “volto.head_title” behavior can be enabled in the generic setup XML definition of a content type (e.g. “/profiles/default/types/MyContentType.xml”):<?xml version="1.0" encoding="UTF-8" ?>
<object i18n:domain="fzj.internet" meta_type="Dexterity FTI" name="MyContentType"

  </property>
  ...
</object>Image scalesThis package introduces new Plone image scales in Plone and redefines a couple of
existing ones. These are know to work well with Volto layout and grid system:icon 32:32
tile 64:64
thumb 128:128
mini 200:65536
preview 400:65536
teaser 600:65536
large 800:65536
larger 1000:65536
great 1200:65536
huge 1600:65536This change is opinionated and may collide with your previously defined ones, so make
sure your add-on’s profiles are applied AFTER this one.Credits and historyThe code of plone.volto has been under active development and is used in production since 2018.
First as kitconcept.voltodemo (deprecated since March, 5th 2020), then as kitconcept.volto.
In September 2021 kitconcept.volto has been renamed to plone.volto and has been contributed to the Plone core as part ofPLIP #2703.ContributorsNoteplace names and roles of the people who contribute to this package
