# Sandbox.Json.TrackedObjectDefinition.AllowedAsRoot

```csharp
bool AllowedAsRoot
```

If true, objects of this type can be the root of the object tree.

## Remarks

Root objects don't require a parent, and they don't need an ID since there can only be one root.
If AllowedAsRoot is false, ParentType must be specified.
