By default, all links for the Sidenav Menu will always. But sometimes you may want to have links show only for certain types of users. For example, maybe you have a membership site that comes with a free trial. For members you may have links to other resources or pages that you do not want your free trial users to see. Or maybe you want to show links simply based on logged in state. To create these "Smart Links", be use the When to show this setting.
