Canvas recently changed the style of the left navigation menu. Previously, buttons hidden from students were light gray with an asterisk next to them. Now, hidden buttons have a small crossed-out eyeball icon next to them. There has been no functionality change, just a visual one.
The syllabus button will be hidden, but students still have access to the Canvas syllabus page because per our template, it is set to the course home page. Students can access this page by clicking “Home” just as they always have. Content items such as assignments, pages, and quizzes should be linked from the modules area so students can access all course content in one place.
