The `truncate()` method returns a Promise that resolves after all items have been removed from the specified collection. `truncate()` runs when the current user is the site owner, or when the method is called with [elevated permissions](https://dev.wix.com/docs/sdk/articles/work-with-the-sdk/about-elevated-permissions.md). > **Note:** `truncate()` also clears multiple-item reference fields in collections referenced by the specified collection. For example, suppose you have a **Movies** collection with an **Actors** field that contains multiple references to items in a People collection. Truncating the **Movies** collection also clears the data in the corresponding multiple-item reference field in the People collection. # Method Permissions: - Write Data Items # Method Permissions Scopes IDs: - SCOPE.DC-DATA.WRITE # Method Code Examples: ## Site owner removes all items from a collection ```javascript import { items } from "@wix/data"; async function truncateItems() { await items.truncate("myCollection") console.log("All items removed"); } ``` ## default ```javascript try { const result = await items.truncate("collection-0.21236182986643115"); return result; } catch (error) { console.error(error); throw error; } ```
