# Layout Editor

> Edit a specific named page layout for a data manager object, with support for adding sections, fields, and components to the layout canvas.

Layout Editor is the page at `/settings/data-manager/:apiName/layouts/:layoutId` that provides a full-page editing interface for a named page layout associated with a specific data manager object.

## Overview

The page resolves both `:apiName` and `:layoutId` from route params. It fetches the target layout via `usePageLayout` and the parent object definition via `useObjectByApiName`. A dynamic breadcrumb (`useBreadcrumbLabel`) is set to the layout's `layout_name`. If either the layout or object is not found, an error state with a back-navigation link to the data manager is shown. The `LayoutEditor` component provides the editing canvas.

This page is accessed from the Data Manager object detail page (`/settings/data-manager/:apiName`).

## Who it's for

Access follows your organization's role and module configuration. SME should confirm intended access.

## Before you start

* The data manager object (`apiName`) and layout (`layoutId`) must already exist.
* Navigate here from the Data Manager object detail page.

## Steps

1. Navigate to **Settings → Data Manager** and open the target object.
2. Select the layout you want to edit from the layouts list to navigate to `/settings/data-manager/:apiName/layouts/:layoutId`.
3. Use the `LayoutEditor` canvas to add, remove, or rearrange sections and fields.
4. Save changes when finished.
5. Use the back button to return to the data manager object detail page.
