--- title: Navigation Menu Items description: Add custom entries to the workspace sidebar — links to saved views or external URLs. icon: "bars" --- A **navigation menu item** is an entry in the left sidebar. Use `defineNavigationMenuItem()` to ship custom sidebar links — typically one per [view](/developers/extend/apps/layout/views) you ship — or to point at external URLs. ```ts src/navigation-menu-items/example-navigation-menu-item.ts import { defineNavigationMenuItem, NavigationMenuItemType } from 'twenty-sdk/define'; import { EXAMPLE_VIEW_UNIVERSAL_IDENTIFIER } from '../views/example-view'; export default defineNavigationMenuItem({ universalIdentifier: '9327db91-afa1-41b6-bd9d-2b51a26efb4c', name: 'example-navigation-menu-item', icon: 'IconList', color: 'blue', position: 0, type: NavigationMenuItemType.VIEW, viewUniversalIdentifier: EXAMPLE_VIEW_UNIVERSAL_IDENTIFIER, }); ``` ## Key points - `type` determines what the menu item links to. Each type pairs with a specific identifier field: | Type | What it does | Required field | |------|--------------|----------------| | `NavigationMenuItemType.VIEW` | Opens a saved view | `viewUniversalIdentifier` | | `NavigationMenuItemType.LINK` | Opens an external URL | `link` | | `NavigationMenuItemType.FOLDER` | Groups nested items under a label | `name` (and child items reference the folder via `folderUniversalIdentifier`) | | `NavigationMenuItemType.OBJECT` | Opens an object's default index page | `targetObjectUniversalIdentifier` | | `NavigationMenuItemType.PAGE_LAYOUT` | Opens a standalone page layout | `pageLayoutUniversalIdentifier` | - `position` controls ordering in the sidebar. - `icon` and `color` are optional and customize how the entry looks. - `folderUniversalIdentifier` is also available on any item to nest it inside a `FOLDER`-type parent. **Common pitfall:** creating an object without an associated view + navigation menu item makes that object invisible to users. Unless it's a technical/internal object, every custom object should have a default view *and* a sidebar entry pointing at it.
