Reply To: Pushing lines to next page when there is big footnotes

The choices in the Type > Document Footnote Options… dialog, specifically in the Layout pane, allow you to determine footnote behavior in your document. Making sure that Allow Split Footnotes is checked (middle of the Footnote Options Layout pane) should help in your case. You’ll also want to pay attention to the Keep Options for the footnotes to make sure that Keep Lines Together All Lines in Paragraph is not selected. If you’re using a paragraph style, you can check the settings there. Otherwise, you can access them from the Paragraph panel or from the menu in top right corner of the Control panel.
