Limit selection to selected object?

Currently when i rectangle select faces or vertices or edges in the scene it also grabs faces or vertices or edges from another mesh that is not selected.

Is there a way to limit making selection to the current selected mesh?

Hi Tiles,

By default, you can only select sub_objects of a selected object.

I Have been looking to see if I can find an option to allow selecting an un-selected objects sub_objects to see if you may of changed options some where, but not found such an option yet.

By default, you can only select sub_objects of a selected object.

Ah, my bad, the objects were combined. I´ve splitted them now. Thanks
