Static boxes are used to separate model structure or controls so they are grouped together.
The image below shows four static boxes, each groups allocations for the various regions.
Note : When moving a static box, the contents within it will also move. To stop this, hold the ALT key when moving.
You can turn any comment into a static box. Set the shape to "Box" and then the text position to "In border at top". You can also change the text alignment.
