Basic Question - Grids dragging things about/Manual/Auto

I want to drag stuff between grid boxes. Explainer video says click object, the right size tools change and use the button to turn from auto to manual and in the video that button sits in the layout section of the tools . I click the element I want to drag (in this case and image block that’s not yet an image just there while I flesh out the layout)…there is no auto/manual button. Where are the auto/manual buttons? What have I missed?
