TreeView.unbindItem

public Action<VisualElement,int> unbindItem;

Description

Callback for unbinding a data item from the VisualElement.

The method called by this callback receives the VisualElement to unbind, and the index of the element to unbind it from.

Note:: Setting this callback without also setting bindItem might cause unexpected behavior. This is because the default implementation of bindItem expects the default implementation of unbindItem.
