Synced viewing modes
Some people like to read a document one chunk at a time, while others prefer to see the whole thing at once. Both options are available. CDISC documents on the Wiki are built as a series of pages, with each section on its own page. The pages are arranged hierarchically to create the structure of the document, with the cover page serving as the top level (or parent page). The cover page also serves as the compiled view of the document: everything below the table of contents on the cover page is actually an automatic reflection of the content, titles, and hierarchy of the sectional pages. Readers who wish to read the document as a single unit can simply start at the top of the cover page and read until the end. Readers who wish to read the document one chunk at a time can access the sectioned pages via the space navigation in the sidebar, by clicking on the heading for the first section (not in the table of contents, though that will take you to the heading, and you can then click on it to reach the first section as its own page), or by jumping to a specific section from the landing page.
There is no difference in content between these two viewing modes, because the compiled view is a mirror of the sectioned view: content from the one is automatically reflected in the other.
