# Content Type Configuration
Defines content types that group related columns and control document behavior and workflows.
Referenced by: SiteCfg.ContentTypes, DocLibCfg.ContentTypes.
# Overview
ContentTypeCfg defines a SharePoint content type, which is a reusable collection of columns with shared properties and behaviors. Content types can be applied to document libraries to control what columns are available and how items are managed.
# Applied when
Content types are created when:
- The parent
SiteCfgis provisioned and references this content type viaContentTypesarray - OR a
DocLibCfgreferences this content type viaContentTypesarray (adds content type to library) - Applied during site or library provisioning; content types are created at the site level and then added to libraries
- All column assignments to the content type (via
Columnsarray) are applied when the content type is created - Retroactive changes to content type structure (adding/removing columns, changing parent content type) may require manual SharePoint administration
# Core settings
# Name
Type: string | Required: Yes
Unique name for this content type. Used in configuration references to identify the content type.
Example: "MatterDocument", "Contract"
# Group
Type: string | Required: No
Content type group for UI organization. Groups related content types in SharePoint UI and settings pages.
Example: "Matter Documents", "Legal Documents"
# Description
Type: string | Required: No
Content type description. Shown in SharePoint content type settings and as a help tooltip.
# ParentContentType
Type: string | Required: No | Default: "Document"
Parent content type name or ID to inherit from. Inherits columns and behaviors from the parent.
Valid parent values:
"Document"(ID: 0x0101) — Standard document"Folder"(ID: 0x0120) — Folder"Document set"(ID: 0x0120D520) — Document set
Important: When this property changes, ContentTypeID is automatically regenerated. Only change the parent if intentional.
# ContentTypeID
Type: string | Required: No | C#: ContentTypeID
Explicit content type ID (advanced usage). Automatically generated from ParentContentType unless explicitly set.
Auto-generated format uses standard SharePoint GUID-based ID generation (e.g., 0x0101{GUID}).
Only override this if you need a specific content type ID that must be preserved across environments. Changes to this ID can break existing document associations.
# FromContentTypeHub
Type: bool | Required: No | Applies When: SharePoint Online only
Inherit from content type hub. When enabled, the content type is pulled from your SharePoint Online content type hub rather than created locally.
# Field configuration
# Fields
Type: string (list) | Required: No
Array of field references with optional visibility settings. Each field can specify flags for Required, Readonly, and Hidden.
Format: "FieldName" or "FieldName=Flag1,Flag2,Flag3"
Example:
["MatterCode", "MatterName=Required", "Status=Readonly", "Notes=Hidden"]
Valid flags:
Required— User must provide a valueReadonly— Field cannot be editedHidden— Field is hidden from the form
# Document set configuration
For document set content types, additional properties:
# DocumentSetAllowedContentTypes
Type: string (list) | Required: No

Example: ["Matter", "Correspondence", "Pleading"]
# DocumentSetSharedFields
Type: string (list) | Required: No
Fields to show at the document set level (not per-document). These fields apply to the entire set, not individual documents.
Example: ["MatterCode", "Status", "Owner"]
# DocumentSetWelcomePageFields
Type: string (list) | Required: No
Fields to display on the document set welcome page. Controls what document set metadata is visible to users opening the set.
