Because
the length of an interactive form containing subforms that are set
to flow content can vary depending on the amount of data displayed
in the form, the form often has more than one page. As a result,
you may want certain subforms (sections) in the form to continue
on subsequent pages.
Using overflow leader and overflow trailer subforms, you can
designate different subforms to precede and follow repeating or
expanding subforms that are likely to carry over to additional pages.
Overflow leaders and trailers are special types of subforms that
you can use in form designs that have a flowable layout. After you
specify a subform as an overflow leader subform in the Binding tab
of the Object palette, the subform appears at the top of each new
page.
For example, you can use the heading row at the top of a table
as an overflow leader subform. Placing the heading row at the top
of a table ensures that it is repeated at the top of each new page,
making the information in the table rows easier to read and follow
from page to page.
Similarly, you can assign an overflow trailer subform to follow
the last occurrence on a page of a repeating or expanding subform
that could possibly span multiple pages.
