Hide Table of Contents/Menu Slide link until slide was viewed Jul 22, 2014 By Darren McNeill Hi, I have been requested to provide the following solution. Show the Table of Contents Menu on the left, but, only display the slide links of the slides that have been viewed. All of the slides are required viewing and they need to be watched in the correct order. Showing the TOC means the user can click on all slides at any time. Is there a way to hide un-viewed slide links in the TOC? Or if you have another solution I would appreciate it.
