Both Print dialog and Export in PDF dialog allow to select which page to print/export. When you want to limit to certain sections of the document, one needs to identify on which page they are. Proposal is to allow the user to select sections/part of the tree of headings and the software will determine which pages to print/export. It can be done by having the option to select headings or by having a window to select the headings and then it populates the Page field to print/export. When reviewing a document (in paper) or sharing it, such function would be very handy.
What about these alternatives: - Selecting in the body of the text the part you need, then using "Selection" in the PDF/Print dialogs - Using the Navigator sidebar deck with Content Navigation View activated, doing a multi-selection of heading, then printing that selection as above - Another workaround: creating a new document that contains only a part of the original as a section: https://ask.libreoffice.org/t/export-only-certain-section/13261 Wouldn't that be sufficient?
Workaround from Stéphane are totally sufficient, thanks!
