What This Skill Covers

How to add, customize, and manage editor tabs in Pimcore Studio UI:

• Tab Manager Architecture - How each element type and subtype has its own tab manager
• IEditorTab Interface - The shape of a tab registration object
• Available Tab Managers - Complete list of tab managers for assets, documents, and data objects
• Tab Registration & Override - Adding or replacing tabs, with permissions and detachable support
• Tab Component Pattern - Building tab content with standard layout components
• Plugin Wiring - Connecting tab extensions to the module system

When to Use This Skill

Use this when:

• Adding a new tab to an asset, document, or data object editor
• Replacing or extending an existing editor tab (e.g., custom preview)
• Controlling tab visibility based on permissions or element state
• Creating tabs that can be detached into their own window
• Need to know which tab manager to target for a specific element subtype

Import Paths

BEFORE writing any import, read CRITICAL-IMPORT-PATHS.md.

All examples use bundle imports (@pimcore/studio-ui-bundle/*). For core development (@sdk/*, @Pimcore/*), see the referenced file.

Tab Manager Architecture

Every element editor in Pimcore Studio is composed of tabs managed by Tab Managers -- injectable services in the DI container. Each element type (asset, document, data-object) has multiple tab managers, one per subtype.

Key Concepts

1. One tab manager per subtype -- e.g., ImageTabManager for image assets, PageTabManager for page documents.
2. Injectable via DI container -- accessed through container.get<T>(serviceIds[...]).
3. Registration order matters -- Built-in tabs are registered first; custom tabs appear after.
4. Tabs are plain objects -- described by an IEditorTab object, not a class.

IEditorTab Interface

Every tab registration uses the IEditorTab interface:

interface IEditorTab {
  /** Unique key identifying the tab. Must not collide with existing tabs. */
  key: string

  /** Display label shown in the tab bar. Can be a string or JSX for custom rendering. */
  label: string | React.JSX.Element

  /** The React component rendered as tab content. */
  children: React.JSX.Element

  /** Icon shown next to the label in the tab bar. */
  icon: React.JSX.Element

  /**
   * Element-level permission required to see this tab.
   * Checked against the element's permissions object.
   * Example: 'properties', 'versions', 'settings'
   */
  workspacePermission?: string

  /**
   * User-level permission required to see this tab.
   * Checked against the current user's global permissions.
   * Example: 'notes_events', 'tags_configuration'
   */
  userPermission?: string

  /**
   * Dynamic visibility function. Return true to hide the tab.
   * Receives the current element as argument.
   */
  hidden?: (element: any) => boolean

  /**
   * Whether this tab can be popped out into a separate window.
   * Defaults to false.
   */
  isDetachable?: boolean
}

Permission Evaluation Order

When a tab has multiple permission fields, all must pass for the tab to be visible:

1. userPermission -- Does the user have this global permission?
2. workspacePermission -- Does the user have this permission on the element?
3. hidden() -- Does the dynamic function return true?

Available Tab Managers

Use the service ID that matches the element subtype you want to extend. Service IDs always follow the pattern '{ElementType}/Editor/{SubType}TabManager'.

Asset Tab Managers

Subtype	Service ID	Type
Image	serviceIds['Asset/Editor/ImageTabManager']	ImageTabManager
Video	serviceIds['Asset/Editor/VideoTabManager']	VideoTabManager
Audio	serviceIds['Asset/Editor/AudioTabManager']	AudioTabManager
Text	serviceIds['Asset/Editor/TextTabManager']	TextTabManager
Document (PDF, etc.)	serviceIds['Asset/Editor/DocumentTabManager']	DocumentTabManager
Archive (ZIP, etc.)	serviceIds['Asset/Editor/ArchiveTabManager']	ArchiveTabManager
Folder	serviceIds['Asset/Editor/FolderTabManager']	FolderTabManager
Unknown	serviceIds['Asset/Editor/UnknownTabManager']	UnknownTabManager

Asset types are imported from @pimcore/studio-ui-bundle/modules/asset.

Document Tab Managers

Subtype	Service ID	Type
Page	serviceIds['Document/Editor/PageTabManager']	PageTabManager
Snippet	serviceIds['Document/Editor/SnippetTabManager']	SnippetTabManager
Email	serviceIds['Document/Editor/EmailTabManager']	EmailTabManager
Link	serviceIds['Document/Editor/LinkTabManager']	LinkTabManager
Hardlink	serviceIds['Document/Editor/HardlinkTabManager']	HardlinkTabManager
Folder	serviceIds['Document/Editor/FolderTabManager']	FolderTabManager

Document types are imported from @pimcore/studio-ui-bundle/modules/document.

Data Object Tab Managers

Subtype	Service ID	Type
Object	serviceIds['DataObject/Editor/ObjectTabManager']	ObjectTabManager
Variant	serviceIds['DataObject/Editor/VariantTabManager']	VariantTabManager
Folder	serviceIds['DataObject/Editor/FolderTabManager']	FolderTabManager

Data object types are imported from @pimcore/studio-ui-bundle/modules/data-object.

IMPORTANT: The FolderTabManager type exists in all three modules (asset, document, data-object). Always import it from the module that matches your target element type — mismatching will cause type errors.

Registering a New Tab

The standard pattern uses AbstractModule.onInit() to get the tab manager from the container and call register().

// File: your-bundle/assets/studio/js/src/modules/image-metadata-tab-extension.tsx
import React from 'react'
import { type AbstractModule, container } from '@pimcore/studio-ui-bundle'
import { serviceIds } from '@pimcore/studio-ui-bundle/app'
import { Icon } from '@pimcore/studio-ui-bundle/components'
import { type ImageTabManager } from '@pimcore/studio-ui-bundle/modules/asset'
import { ImageMetadataTab } from '../components/image-metadata-tab/image-metadata-tab'

export const ImageMetadataTabExtension: AbstractModule = {
  onInit (): void {
    const imageTabManager = container.get<ImageTabManager>(
      serviceIds['Asset/Editor/ImageTabManager']
    )

    imageTabManager.register({
      key: 'my-bundle.image-metadata',
      label: 'Metadata',
      icon: <Icon value="info-circle" />,
      children: ,

      
      : ,

      
      : ,

      
      :  element?. !== ,

      
      : 
    })
  }
}

To target a different element type or subtype, change three things:

1. The type import (ImageTabManager -> your target)
2. The service ID ('Asset/Editor/ImageTabManager' -> your target from the tables above)
3. The import module path (modules/asset -> modules/document or modules/data-object)

Registering Tabs for Multiple Subtypes

If your tab should appear across multiple subtypes, define it once and register with each tab manager:

export const UniversalAssetTabExtension: AbstractModule = {
  onInit (): void {
    const customTab = {
      key: 'my-bundle.universal-tab',
      label: 'Universal Tab',
      icon: <Icon value="star" />,
      children: <UniversalTabContent />
    }

    container.get<ImageTabManager>(serviceIds['Asset/Editor/ImageTabManager']).register(customTab)
    container.get<VideoTabManager>(serviceIds['Asset/Editor/VideoTabManager']).register(customTab)
    container.get<DocumentTabManager>(serviceIds['Asset/Editor/DocumentTabManager']).register(customTab)
  }
}

Overriding an Existing Tab

Replace an existing tab's content while preserving its key, label, icon, and permissions.

// File: your-bundle/assets/studio/js/src/modules/custom-preview-tab.tsx
import { type AbstractModule, container } from '@pimcore/studio-ui-bundle'
import { serviceIds } from '@pimcore/studio-ui-bundle/app'
import { type ObjectTabManager } from '@pimcore/studio-ui-bundle/modules/data-object'
import { CustomPreviewTab } from '../components/custom-preview-tab/custom-preview-tab'

export const CustomPreviewOverride: AbstractModule = {
  onInit (): void {
    const objectTabManager = container.get<ObjectTabManager>(
      serviceIds['DataObject/Editor/ObjectTabManager']
    )

    // Always check that the tab exists — core may rename or remove it
    const previewTab = objectTabManager.getTab('preview')

    if (previewTab === undefined) {
      console.warn('[my-bundle] Tab "preview" not found. Override skipped.')
      return
    }

    // Re-register with the same key but new children (and optionally more)
    objectTabManager.register({
      ...previewTab,
      children: <CustomPreviewTab />,
      
      
      
    })
  }
}

How it works:

1. getTab('preview') retrieves the existing tab registration.
2. Spread ...previewTab copies all existing properties.
3. children replaces only the rendered content.
4. register() with an existing key overwrites the previous registration.

Tab Component Pattern

Tab content should use the standard layout pattern with Content and Header components. Access the current element via useElementContext() and element-specific draft hooks.

// File: your-bundle/assets/studio/js/src/components/asset-info-tab/asset-info-tab.tsx
import React from 'react'
import { Content, Header } from '@pimcore/studio-ui-bundle/components'
import { useElementContext } from '@pimcore/studio-ui-bundle/modules/element'
import { useAssetDraft } from '@pimcore/studio-ui-bundle/modules/asset'
import { useTranslation } from 'react-i18next'

export const AssetInfoTab = (): React.JSX.Element => {
  const { t } = useTranslation()
  const { id } = useElementContext()
  const { asset } = useAssetDraft(id)

  if (asset === undefined) {
    return <Content padded>Loading...</Content>
  }

  return (
    <Content padded>
      <Header title={t('my-bundle.asset-info.title')} />
      <p>Type: {asset.type}
      Size: {asset.fileSize}
    
  )
}

For tabs with toolbars or forms, wrap in <Flex vertical className="absolute-stretch"> and add a <Toolbar> alongside <Content>. For form-based tabs, use FormKit — see pimcore-studio-ui-forms-antd.

Plugin Wiring

Tab extensions must be wired into the plugin system to be loaded.

// File: your-bundle/assets/studio/js/src/plugin.ts
import { type IAbstractPlugin } from '@pimcore/studio-ui-bundle'
import { ImageMetadataTabExtension } from './modules/image-metadata-tab-extension'
import { CustomPreviewOverride } from './modules/custom-preview-tab'

export const MyBundlePlugin: IAbstractPlugin = {
  name: 'MyBundlePlugin',

  onStartup ({ moduleSystem }) {
    moduleSystem.registerModule(ImageMetadataTabExtension)
    moduleSystem.registerModule(CustomPreviewOverride)
  }
}

Lifecycle: Plugin vs Module

1. Plugin.onStartup()  -> Register modules via moduleSystem.registerModule()
                          (DO NOT register tabs here -- too early!)
2. Module.onInit()     -> Register tabs via tabManager.register()
                          (This is the correct place)
3. Application renders -> Tabs visible in element editors

Rule: Always register tabs in Module.onInit(), never in Plugin.onStartup().

Common Mistakes

Wrong Service ID Format

// WRONG
serviceIds['AssetFolderTabManager']  // Does not exist

// CORRECT — always '{ElementType}/Editor/{SubType}TabManager'
serviceIds['Asset/Editor/FolderTabManager']

Registering Tabs in Plugin onStartup (Too Early)

// WRONG — tab managers may not be ready, registration may fail or be overwritten
export const MyPlugin: IAbstractPlugin = {
  name: 'MyPlugin',
  onStartup ({ moduleSystem }) {
    const tabManager = container.get<ImageTabManager>(serviceIds['Asset/Editor/ImageTabManager'])
    tabManager.register({ ... })
  }
}

// CORRECT — register the module in the plugin, register tabs in Module.onInit()
export const MyPlugin: IAbstractPlugin = {
  name: 'MyPlugin',
  onStartup ({ moduleSystem }) {
    moduleSystem.registerModule(MyTabModule)
  }
}

Mismatched Tab Manager Type and Element Module

// WRONG — FolderTabManager imported from asset but service ID is for document
import { type FolderTabManager } from '@pimcore/studio-ui-bundle/modules/asset'
container.get<FolderTabManager>(serviceIds['Document/Editor/FolderTabManager'])

// CORRECT — match the import module to the element type
import { type FolderTabManager } from '@pimcore/studio-ui-bundle/modules/document'
container.get<FolderTabManager>(serviceIds['Document/Editor/FolderTabManager'])

Tab Key Collision

// WRONG — generic keys may collide with built-in tabs
key: 'settings'

// CORRECT — namespace your keys
key: 'my-bundle.settings'

Not Handling Missing Tab During Override

// WRONG — getTab() may return undefined
const previewTab = objectTabManager.getTab('preview')
objectTabManager.register({ ...previewTab, children: <CustomPreview /> })

// CORRECT — check before spreading
const previewTab = objectTabManager.getTab('preview')
if (previewTab === undefined) {
  console.warn('[my-bundle] Tab not found. Override skipped.')
  return
}
objectTabManager.register({ ...previewTab, children: <CustomPreview /> })

Forgetting Icon or React Imports

// CORRECT — both imports required when using JSX
import React from 'react'
import { Icon } from '@pimcore/studio-ui-bundle/components'
