### Remarks

This callback receives the [HierarchyViewItem](/engine/6000.5/script-reference/unity/hierarchy/hierarchyviewitem.md) to create the context menu for and the [DropdownMenu](/engine/6000.5/script-reference/unityengine/uielements/dropdownmenu.md) to populate. If the user right-clicks in empty space, the callback receives null for the view item.
