Transform tool handles greyed out, says "static"

When I am running in the editor, certain game objects have a greyed out transform tool gizmo (see screenshot) and I cannot move them while the game is running. Why is this and how can I get around it? What does “static” mean in this context?

Cheers.

You marked one or more properties of the object as static in the inspector; since it’s static it can’t be moved at runtime.
