+## Details
+
+'NodeRestoreDirective' directive takes a selection of `DeletedNodeEntry[]` and restores them in their original location.
+If the original location doesn't exist anymore, then they remain in the trash list.
+
+For single node restore, there is action to jump to the location where the node has been restored and for this `location` is used to specify the route path where the list of nodes are rendered
