Lock a folder worldOutliner

I don’t know if that annoys you too, but I’m looking for as a certain number of software the way to lock a folder.
For example :
in the worldOutliner, I have a folder that groups all my geometries, I would like to lock it:

  1. To prevent the folder from unfolding all of its contents, when I click on an item it contains.
  2. inadvertently prevent moving or modifying a static mesh

Best regards

Best regards

I found the solution:

Select the object in the World Outliner or in the viewport> right click> Transform> Lock actor movement

To copy and move an object Click on the object + alt: will create a copy

To copy paste a location, rotation, scale
Right click on the names of these attributes found in the Transform panel.

Best regards
