That is a very outdated version of the user guide, by the look of it.
We are working to make the latest version more accessible.
Your vague problem description is not at all helpful, and is not likely to lead to any change.

Please accept my apologies for the lack of detail in my previous post which was tediously, tapped on a tablet.

I have just installed the latest VI 4.0-Dev version and the User Guide display problem still exists for an iPad Mini 2

To demonstrate the problem load the two following User Guides and shrink the browser width to less than 768px or until the "Hamburger" appears.

CI 3.06: - displays correctly

CI 4.0-Dev: only uses half the web-page
