description: Customize record detail pages — tabs, widgets, and where front components render — using definePageLayout and definePageLayoutTab.

|
A **page layout** controls how a record's detail page is arranged: which tabs appear and what widgets they contain. Use `definePageLayout()` to declare a layout for an object you own, or `definePageLayoutTab()` to add a single tab to a layout that already exists (yours or a standard Twenty one).
|
|
|
|
| Use case | Entity |
|
|
|----------|--------|
|
|
| Define the entire layout for a record page on an object you own | `definePageLayout` |
|
|
| Add one tab to an existing layout (your own object, or a standard one) | `definePageLayoutTab` |
|
|
|
|
## definePageLayout
|
|
|
|
Use this when you own the entire detail page — typically for a custom object you defined yourself.
|
|
|
|
```ts src/page-layouts/example-record-page-layout.ts
|
|
import { definePageLayout, PageLayoutTabLayoutMode } from 'twenty-sdk/define';
|
|
import { EXAMPLE_OBJECT_UNIVERSAL_IDENTIFIER } from '../objects/example-object';
|
|
import { HELLO_WORLD_FRONT_COMPONENT_UNIVERSAL_IDENTIFIER } from '../front-components/hello-world';
|
|
|
|
export default definePageLayout({
|
|
universalIdentifier: '203aeb94-6701-46d6-9af1-be2bbcc9e134',
|
|
name: 'Example Record Page',
|
|
type: 'RECORD_PAGE',
|
|
objectUniversalIdentifier: EXAMPLE_OBJECT_UNIVERSAL_IDENTIFIER,
|
|
tabs: [
|
|
{
|
|
universalIdentifier: '6ed26b60-a51d-4ad7-86dd-1c04c7f3cac5',
|
|
title: 'Hello World',
|
|
position: 50,
|
|
icon: 'IconWorld',
|
|
layoutMode: PageLayoutTabLayoutMode.CANVAS,
|
|
widgets: [
|
|
{
|
|
universalIdentifier: 'aa4234e0-2e5f-4c02-a96a-573449e2351d',
|
|
title: 'Hello World',
|
|
type: 'FRONT_COMPONENT',
|
|
configuration: {
|
|
configurationType: 'FRONT_COMPONENT',
|
|
frontComponentUniversalIdentifier:
|
|
HELLO_WORLD_FRONT_COMPONENT_UNIVERSAL_IDENTIFIER,
|
|
},
|
|
},
|
|
],
|
|
},
|
|
],
|
|
});
|
|
```
|
|
|
|
### Key points
|
|
|
|
- `type` is typically `'RECORD_PAGE'` to customize the detail view of a specific object.
|
|
- `objectUniversalIdentifier` specifies which object this layout applies to.
|
|
- Each `tab` defines a section of the page with a `title`, `position`, and `layoutMode` (`CANVAS` for free-form layout).
|
|
- Each `widget` inside a tab can render a [front component](/developers/extend/apps/layout/front-components), a relation list, or other built-in widget types.
|
|
- `position` on tabs controls their order. Use higher values (e.g., 50) to place custom tabs after built-in ones.
|
|
|
|
## definePageLayoutTab
|
|
|
|
Use this when you only want to **add** a tab to an existing layout — for example, an analytics tab on the standard Company page, or an AI summary tab attached to your own object's layout.
|
|
|
|
```ts src/page-layouts/example-extra-tab.ts
|
|
import {
|
|
definePageLayoutTab,
|
|
PageLayoutTabLayoutMode,
|
|
} from 'twenty-sdk/define';
|
|
import { HELLO_WORLD_FRONT_COMPONENT_UNIVERSAL_IDENTIFIER } from '../front-components/hello-world';
|
|
|
|
const COMPANY_RECORD_PAGE_LAYOUT_UNIVERSAL_IDENTIFIER =
|
|
'20202020-ab01-4001-8001-c0aba11c0100';
|
|
|
|
export default definePageLayoutTab({
|
|
universalIdentifier: 'b1b2b3b4-b5b6-4000-8000-000000000001',
|
|
pageLayoutUniversalIdentifier:
|
|
COMPANY_RECORD_PAGE_LAYOUT_UNIVERSAL_IDENTIFIER,
|
|
title: 'Hello World',
|
|
position: 1000,
|
|
icon: 'IconWorld',
|
|
layoutMode: PageLayoutTabLayoutMode.CANVAS,
|
|
widgets: [
|
|
{
|
|
universalIdentifier: 'b1b2b3b4-b5b6-4000-8000-000000000002',
|
|
title: 'Hello World',
|
|
type: 'FRONT_COMPONENT',
|
|
configuration: {
|
|
configurationType: 'FRONT_COMPONENT',
|
|
frontComponentUniversalIdentifier:
|
|
HELLO_WORLD_FRONT_COMPONENT_UNIVERSAL_IDENTIFIER,
|
|
},
|
|
},
|
|
],
|
|
});
|
|
```
|
|
|
|
### Key points
|
|
|
|
- `pageLayoutUniversalIdentifier` is **required** and must point to a page layout that already exists at install time — either a standard Twenty layout or one defined by your own app. Cross-app references to layouts owned by another installed app are not supported today. When the parent layout is missing, installation fails with a clear validation error.
|
|
- `widgets` are scoped to this tab only — they reference [front components](/developers/extend/apps/layout/front-components), views, etc. exactly like widgets defined inline in `definePageLayout`.
|
|
- `position` controls ordering against existing tabs on the targeted layout. Pick a value that places your tab where you want it relative to built-in tabs.
|
|
- Use this instead of `definePageLayout` when you only want to add to an existing layout. Use `definePageLayout` when you own the entire layout.
