- From the Space tools menu, select Content Tools and then the Export tab. The Export Formats page appears.
- Select PDF. If you do not have this option, contact Application Support at NCIAppSupport@nih.gov.
- Click Next. The Export PDF Options page appears.
- If you want to include page numbers, select Include Page Numbers.
- Select Custom Export. A panel opens listing all pages in the wiki space to which you have access.
- Select the checkboxes for the pages you want to export.
- To clear or select all checkboxes, click the All pages checkbox.
- To clear or select all of the checkboxes for an entire page family, click the checkbox for the parent page.
- Scroll to the bottom of the page and then click Export. The Exporting Space as PDF - In Progress page appears. When the export completes, "Your PDF file is ready to go" appears below the progress bar.
