Subforms can be placed anywhere in a form design. However, when a large amount of data is merged, the subform may expand beyond the bottom edge of the rendered page.To deal with this issue, you can either enable a page break in the middle of the subform or force the entire subform to be rendered starting at the top of the next rendered page. Forcing a subform to the next page ensures that any nested subforms are displayed together on the same page.When data is merged, the content of a subform is placed within the confines of content areas only. In cases where a relatively large amount of data needs to be merged with any of the objects in a subform, a subform may span multiple form pages.When a form page is filled, an additional identical page is rendered automatically. The subform continues to be placed on the new page unless you explicitly direct the flow to a different content area or master page. When more than one content area or master page exists in the same form, you can specify whether a subform will be placed in a particular content area or positioned according to the specified master page.
