# Editing Existing Content

## Content Within the Tree View

When you are looking to edit content, locate the ***page*** you want to edit in the Content tree on the left-side of the screen.

To edit existing content, follow these steps:

1. Go to the **Content** section.
2. Select the page in the section tree you wish to edit. The content of the page is loaded in the right-side editor.
3. Edit the contents of the page.
4. Click **Save** to save the edits without publishing it.
5. Click **Save and preview** to preview the changes.
6. Click **Save and publish** to publish the changes. For more information, see the [Save and Publishing Pages](/umbraco-cms/get-started/backoffice-essentials/creating-saving-and-publishing-content.md#saving-and-publishing-pages) article.

## View Page Layout

By default, you can view Page layouts in two ways: in a List or in a Grid.

### List

When you [enable Collection](#enabling-collection) on a page, its child pages are no longer shown as nested items in the content tree. Instead, the parent page appears as a single node in the tree. Selecting it displays all of its child pages in a list view within the main content area. For more information, see the [Collection](/umbraco-cms/model-your-content/property-editors/built-in-umbraco-property-editors/collection.md) article.

### Grid

You can switch to the grid view by clicking the ![layout](/files/Q6HeDgKYFPycqjLjfvGD) icon in the top-right of the screen:

3. Go to the **Structure** tab.
4. Click **Configure as a Collection** in the Collections field.
5. Select **List View - Content**.
6. Click **Save**.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.umbraco.com/umbraco-cms/get-started/backoffice-essentials/editing-existing-content.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
