# Read-only mode

In certain situations, Vertex graphs can be opened in read-only mode.
In read-only mode, the following restrictions are applied:

* New objects cannot be added to the graph (including via Search Around).
* Graph nodes cannot be re-arranged (whether by drag-and-drop or other methods).
* The toolbar at the top of the page is hidden.

## When are Vertex graphs opened in read-only mode?

Below is a non-exhaustive list of the situations where a graph is opened in read-only mode.

* When a graph is embedded in Workshop and the read-only mode setting is explicitly enabled in the [widget configuration](../embed-graph-workshop/index.md#configure-the-widget).
* When a graph is opened in [Carbon](../../carbon/overview/index.md).
* When a graph is embedded in [Notepad](../../notepad/widgets-vertex-graph/index.md).
