- If the shelf appears in a separate window and you want to restore it at its default position at the top of the viewport, go to the Workspace field and choose Reset Current Workspace from the list.
To hide the Maya shelf
- Select Shelf. and disable
- You can also tear off the shelf by dragging the double line at its left edge so it is a separate window and then closing the window.
