In SharePoint 2013, you can manage the navigation using
managed metadata or term store. This can be done using the Navigation and Term-Driven Pages
tabs available for the managed metadata term. Here you will see how to enable
those tabs for the managed metadata term. I have a team site where I have created
a local term set named Site Metadata (Go to Site Settings -> Site
Administration -> Term Store Management).
Select Site Metadata term set,
click on INTENDED USE tab. Select Use this Term Set for Site Navigation and
then click on Save. Now you could be able to see the Navigation and Term-Driven
Pages tabs for the term which can be used to manage the navigation.
