# GraphOptions

> Flags that define configuration options that affect the behavior and capabilities of a Graph class.

## Definition

* **Type:** Enum
* **Namespace:** [Unity.GraphToolkit.Editor](/engine/6000.6/script-reference/unity/graphtoolkit/editor.md)
* **Assembly:** UnityEditor

```csharp
[Flags]
public enum GraphOptions
```

## Remarks

Use the [GraphOptions](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphoptions.md) enum in conjunction with the [GraphAttribute](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphattribute.md) to customize how a graph behaves, including support for subgraphs and automatic node discovery. The default value is [GraphOptions.Default](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphoptions/default.md), which enables standard behavior such as allowing nodes defined in the same assembly as the graph to be automatically included in the graph item library. Combine flags to customize behavior. This enum is marked with FlagsAttribute, so you can combine values using bitwise operations to enable multiple options.

This example keeps the default behavior and adds support for subgraphs by enabling [GraphOptions.SupportsSubgraphs](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graphoptions/supportssubgraphs.md).

## Examples

```csharp
[Graph("mygraph", GraphOptions.SupportsSubgraphs)]
public class MyGraph : Graph { }
```
