# Manage Virtual Objects

{% hint style="info" %}
This article describes the method to update virtual objects via the UI. If you intend to develop a workflow to update via API instead, check out our [Public API documentation](/public-api/overview/index/virtual-sources.md).
{% endhint %}

Virtual objects are the assets that live under a virtual source — schemas, tables, columns, data jobs, data tasks, dashboards, and charts. You create and manage them using the **Asset Tree Editor**, which auto-saves every change as you make it.

Open the Asset Tree Editor from the **virtual source landing page** or from any **virtual asset's detail page**. The editor opens scoped to wherever you launched it from — from the virtual source you see all object types across four tabs (Schemas, Data Jobs, Dashboards, Charts); from an individual asset you see that asset and its children.

## Add an object

Each tab has an **Add virtual \[type]** button that creates a new row at the top of the list. Enter a name and click away to save. To add a child object (e.g. a table under a schema), expand the parent row first — the **Add child** button appears inside it.

## Edit an object

Click any field in a row to edit it. Changes save automatically when you click away. For the **Definition** field, clicking it opens a markdown editor modal where you write and save the content.

## Delete an object

Click the delete icon on any row and confirm in the modal. Deleting a parent object (e.g. a Schema) also removes all its children.

{% hint style="warning" %}
Deletion is irreversible — the object and all its metadata are removed from the Catalog, lineage, and search results.
