Reordering layout parts
You can change the order of only the body and subsummary parts; other parts, like the header and footer, must appear in a specific order, so they can't be moved. For example, move a subsummary part above the body to see subtotals first.
To reorder layout parts:
In Layout mode, choose Layouts menu > Part Setup.
A part that can't be moved has a lock icon to the left of its name.
Click Done.
FileMaker Pro moves all the fields and objects in the part and maintains its proportions.
While working in Layout mode, you can quickly reorder a part directly on the layout by clicking the Selection tool Selection tool in the status toolbar and Shift-dragging the part label (or the line that marks the bottom of the part).
