NodeType Definition Reference

THe manual to understand NodeType definitions can be found in the Neos Docs (https://docs.neos.io/cms/manual/content-repository/nodetype-definition).

The following options are allowed for defining a NodeType:

abstract

A boolean flag, marking a node type as abstract. Abstract node types can never be used standalone, they will never be offered for insertion to the user in the UI, for example.

Abstract node types are useful when using inheritance and composition, so mark base node types and mixins as abstract.

aggregate

A boolean flag, marking a node type as aggregate. If a node type is marked as aggregate, it means that:

  • the node type can “live on its own”, i.e. can be part of an external URL
  • when moving this node, all node variants are also moved (across all dimensions)
  • Recursive copying only happens inside this aggregate, and stops at nested aggregates.

The most prominent aggregate is Neos.Neos:Document and everything which inherits from it, like Neos.NodeTypes:Page.

superTypes

An array of parent node types as keys with a boolean value:

'Neos.Neos:Document':
  superTypes:
    'Acme.Demo.ExtraMixin': true

'Neos.Neos:Shortcut':
  superTypes:
    'Acme.Demo.ExtraMixin': false
constraints

Constraint definitions stating which nested child node types are allowed. Also see the dedicated chapter node-constraints for detailed explanation:

constraints:
  nodeTypes:
    # ALLOW text, DISALLOW Image
    'Neos.NodeTypes:Text': true
    'Neos.NodeTypes:Image': false
    # DISALLOW as Fallback (for not-explicitly-listed node types)
    '*': false
childNodes

A list of child nodes that are automatically created if a node of this type is created. For each child the type has to be given. Additionally, for each of these child nodes, the constraints can be specified to override the “global” constraints per type. Here is an example:

childNodes:
  someChild:
    type: 'Neos.Neos:ContentCollection'
    constraints:
      nodeTypes:
        # only allow images in this ContentCollection
        'Neos.NodeTypes:Image': true
        '*': false

By using position, it is possible to define the order in which child nodes appear in the structure tree. An example may look like:

'Neos.NodeTypes:Page':
  childNodes:
    'someChild':
      type: 'Neos.Neos:ContentCollection'
      position: 'before main'

This adds a new ContentCollection called someChild to the default page. It will be positioned before the main ContentCollection that the default page has. The position setting follows the same sorting logic used in Fusion (see the Fusion Reference).

label

When displaying a node inside the Neos UI (e.g. tree view, link editor, workspace module) the label option will be used to generate a human readable text for a specific node instance (in contrast to the ui.label which is used for all nodes of that type).

The label option accepts an Eel expression that has access to the current node using the node context variable. It is recommended to customize the label option for node types that do not yield a sufficient description using the default configuration.

Example:

'Neos.Demo:Flickr':
  label: ${'Flickr plugin (' + q(node).property('tags') + ')'}
generatorClass
Alternatively the class of a node label generator implementing Neos\ContentRepository\Domain\Model\NodeLabelGeneratorInterface can be specified as a nested option.
options

Options for third party-code, the Content-Repository ignores those options but Neos or Packages may use this to adjust their behavior.

fusion

Options to control the behavior of fusion-for a specific nodeType.

prototypeGenerator

The class that is used to generate the default fusion-prototype for this nodeType.

If this option is set to a className the class has to implement the interface \Neos\Neos\Domain\Service\DefaultPrototypeGeneratorInterface and is used to generate the prototype-code for this node.

If options.fusion.prototypeGenerator is set to null no prototype is created for this type.

By default Neos has generators for all nodes of type Neos.Neos:Node and creates protoypes based on Neos.Fusion:Template. A template path is assumed based on the package-prefix and the nodetype-name. All properties of the node are passed to the template. For the nodeTypes of type Neos.Neos:Document, Neos.Neos:Content and Neos.Neos:Plugin the corresponding prototype is used as base-prototype.

Example:

prototype(Vendor.Site:Content.SpecialNodeType) < prototype(Neos.Fusion:Content) {
  templatePath = 'resource://Vendor.Site/Private/Templates/NodeTypes/Content.SpecialNodeType.html'
  # all properties of the nodeType are passed to the template
  date = ${q(node).property('date')}
  # inline-editable strings additionally get the convertUris processor
  title = ${q(node).property('title')}
  title.@process.convertUris = Neos.Neos:ConvertUris
}
ui

Configuration options related to the user interface representation of the node type

label
The human-readable label of the node type
group

Name of the group this content element is grouped into for the ‘New Content Element’ dialog. It can only be created through the user interface if group is defined and it is valid.

All valid groups are given in the Neos.Neos.nodeTypes.groups setting

position
Position inside the group this content element is grouped into for the ‘New Content Element’ dialog. Small numbers are sorted on top.
icon

This setting defines the icon that the Neos UI will use to display the node type.

Legacy: In Neos versions before 4.0 it was required to use icons from the Fontawesome 3 or 4 versions, prefixed with “icon-“

Current: In Neos 4.0, Fontawesome 5 was introduced, enabling the usage of all free Fontawesome icons: https://fontawesome.com/icons?d=gallery&m=free Those can still be referenced via “icon-[name]”, as the UI includes a fallback to the “fas” prefix-classes. To be sure which icon will be used, they can also be referenced by their icon-classes, e.g. “fas fa-check”.

help

Configuration of contextual help. Displays a message that is rendered as popover when the user clicks the help icon in an insert node dialog.

message
Help text for the node type. It supports markdown to format the help text and can be translated (see translate-nodetypes).
thumbnail

This is shown in the popover and can be supplied in two ways:

  • as an absolute URL to an image (http://static/acme.com/thumbnails/bar.png)
  • as a resource URI (resource://AcmeCom.Website/NodeTypes/Thumbnails/foo.png)
If the thumbnail setting is undefined but an image matching the nodetype name

is found, it will be used automatically. It will be looked for in <packageKey>/Resources/Public/NodeTypes/Thumbnails/<nodeTypeName>.png with packageKey and nodeTypeName being extracted from the full nodetype name like this:

AcmeCom.Website:FooWithBar -> AcmeCom.Website and FooWithBar

The image will be downscaled to a width of 342 pixels, so it should either be that size to be placed above any further help text (if supplied) or be half that size for the help text to flow around it.

inlineEditable
If true, it is possible to interact with this Node directly in the content view. If false, an overlay is shown preventing any interaction with the node. If not given, checks if any property is marked as ui.inlineEditable.
inspector

These settings configure the inspector in the Neos UI for the node type

tabs

Defines an inspector tab that can be used to group property groups of the node type

label
The human-readable label for this inspector tab
position
Position of the inspector tab, small numbers are sorted on top
icon

This setting define the icon to use in the Neos UI for the tab

Currently it’s only possible to use a predefined selection of icons, which are available in Font Awesome http://fortawesome.github.io/Font-Awesome/3.2.1/icons/.

groups

Defines an inspector group that can be used to group properties of the node type

label
The human-readable label for this inspector group
position
Position of the inspector group, small numbers are sorted on top
icon
This setting define the icon to use in the Neos UI for the group
tab
The tab the group belongs to. If left empty the group is added to the default tab.
collapsed
If the group should be collapsed by default (true or false). If left empty, the group will be expanded.
creationDialog
Creation dialog elements configuration. See node-creation-dialog for more details.
properties

A list of named properties for this node type. For each property the following settings are available.

Note

Your own property names should never start with an underscore _ as that is used for internal properties or as an internal prefix.

type
Data type of this property. This may be a simple type (like in PHP), a fully qualified PHP class name, or one of these three special types: DateTime, references, or reference. Use DateTime to store dates / time as a DateTime object. Use reference and references to store references that point to other nodes. reference only accepts a single node or node identifier, while references accepts an array of nodes or node identifiers.
defaultValue
Default value of this property. Used at node creation time. Type must match specified ‘type’.
ui

Configuration options related to the user interface representation of the property

label
The human-readable label of the property
help

Configuration of contextual help. Displays a message that is rendered as popover when the user clicks the help icon in the inspector.

message
Help text for this property. It supports markdown to format the help text and can be translated (see translate-nodetypes).
reloadIfChanged
If true, the whole content element needs to be re-rendered on the server side if the value changes. This only works for properties which are displayed inside the property inspector, i.e. for properties which have a group set.
reloadPageIfChanged
If true, the whole page needs to be re-rendered on the server side if the value changes. This only works for properties which are displayed inside the property inspector, i.e. for properties which have a group set.
inlineEditable
If true, this property is inline editable, i.e. edited directly on the page.
aloha
Legacy configuration of rich text editor, works for the sake of backwards compatibility, but it is advised to use inline.editorOptions instead.

inline

editor
A way to override default inline editor loaded for this property. Two editors are available out of the box: ckeditor (loads CKeditor4) and ckeditor5 (loads CKeditor5). The default editor is configurable in Settings.yaml under the key Neos.Neos.Ui.frontendConfiguration.defaultInlineEditor. It is strongly recommended to start using CKeditor5 today, as the CKeditor4 integration will be deprecated and removed in the future versions. Additional custom inline editors are registered via the inlineEditors registry. See ui-extensibility for the detailed information on the topic.
editorOptions

This section controls the text formatting options the user has available for this property.

Note: When using inline.editorOptions anything defined under the legacy aloha key for a property is ignored. Keep this in mind when using supertypes and mixins.

placeholder
A text that is shown when the field is empty. Supports i18n.
autoparagraph
When configured to false, automatic creation of paragraphs is disabled for this property and <enter> key would create soft line breaks instead (equivalent to configuring an editable on a span tag).
linking
A way to configure additional options available for a link, e.g. target or rel attributes.
formatting
Various formatting options (see example below for all available options).

Example:

inline:
  editorOptions:
    placeholder: i18n
    autoparagraph: true
    linking:
      anchor: true
      title: true
      relNofollow: true
      targetBlank: true
    formatting:

      table: true
      ol: true
      ul: true
      a: true
inspector

These settings configure the inspector in the Neos UI for the property.

group

Identifier of the inspector group this property is categorized into in the content editing user interface. If none is given, the property is not editable through the property inspector of the user interface.

The value here must reference a groups configured in the ui.inspector.groups element of the node type this property belongs to.

position
Position inside the inspector group, small numbers are sorted on top.
editor
Name of the JavaScript Editor Class which is instantiated to edit this element in the inspector.
editorOptions
A set of options for the given editor, see the Property Editor Reference.
editorListeners
Allows to observe changes of other properties in order to react to them. For details see depending-properties
validation
A list of validators to use on the property. Below each validator type any options for the validator can be given. See below for more information.

Tip

Unset a property by setting the property configuration to null (~).
