When I'm on my iPhone and I pick a menu option that does not have a hyperlink nothing happens, it is confusing IMO.
Please see this video.

Unfortunately, there is nothing that can be done in relation to the referenced article to solve the issue. The choice to use non-linked nodes in the TOC is an organizational decision.
This is very interesting finding. @ShevaDas Can you take care the issue?
@spottedmahn Thanks for the feedback! I agree this is confusing. We're looking at some big updates to our TOC design and site structure and will make sure this is addressed as those roll out.
We have released an updated mobile view, that solves this problem.
That's great, thanks! 馃帀
