So I am wanting 3 different navigations and I only see how to add 2 though in the snippet area in Design Manager.
I am comfortable with C# but not very knowledgable in Sharepoint. Does anyone know how to grab a specific term set by reference ID?
First you create a TaxonomySession for the current site:
Then you can use the TermStores Property to look up your term store using its GUID:
You can also do the lookup based on the term store name if that is easier to use.
