# CanBeParent(TreeViewItem)

> Override this method to control which items are allowed to be parents.

## Definition

* **Type:** Method
* **Namespace:** [UnityEditor.IMGUI.Controls](/engine/6000.5/script-reference/unityeditor/imgui/controls.md)
* **Assembly:** UnityEditor.CoreModule

> **Warning:**
>
> **Removed.** TreeView is now deprecated. You can likely now use TreeView\\\<int\\> instead and not think more about it. But if you were using that identifier to store InstanceID data, you should instead opt to upgrade your TreeViews to use TreeView\\\<InstanceID\\> to get the proper typing.

```csharp
protected virtual bool CanBeParent(TreeViewItem item)
```

### Parameters

**** (\[TreeViewItem]\(/engine/6000.5/script-reference/unityeditor/imgui/controls/treeviewitem)): Can this item be a parent?

### Returns

| Type                                                          | Description |
| ------------------------------------------------------------- | ----------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) |             |

### Remarks

This is called internally by the TreeView to determine dragging behavior. For list views this function should just return false to prevent any reparenting. Default behavior: returns true.
