# Extra locking options As you edit a BlackBox in Prefab Mode, you will notice some extra options under the Options foldout:

These options allow you to customise how the Prefab behaves.

Property	Function
Hide Transform	When the Prefab is locked, the Transform (or RectTransform) component is hidden too. In addition, the Prefab cannot be moved, scaled or rotated in the scene view.
Keep Unlocked	Note: Having both of these options off is the default scenario, where the Prefab behaves as locked regardless of where it's used.
When Nested	When the Prefab is nested under another Prefab, it is shown as unlocked even if its Locked property is set to true.
If Variant Root	When a Variant is created out of this Prefab and the Variant is being edited, the Prefab root shows as unlocked even if the original Prefab was set to be locked.
Selection Type	The substitute selection mesh to allow selecting children made invisible by BlackBox. (more details)
