I have a problem related to export to pdf in Gantt. When Gantt left side is expanded, and I export to pdf, everything is ok, and all columns are present in exported pdf (see expandedDip.png and expandedDipPdf.png). But when i collapsed it, some columns are not visible in exported pdf (see collapsedDip.png, collapsedDipPdf1.png and collapsedDipPdf2.png). How can I solve this problem? Can I apply scroll for example, or another solution for this?
