Q: When there are more than two free layouts in the header, how to display only one free layout floating?

A: 1) When there are more than two free layouts in the header, turn off the header floating: header - properties - off (open floating), as shown in the figure

2) Click Free Layout. If only one of the free layouts is enabled to float, only the details of the free layout with the floating enabled will be displayed after saving the preview.
