The Web Part offers an additional content navigation to browse the corporate knowledge hierarchically - cross site-collection and independent of the content store's structure. Terms or tags can be linked to tag profile pages, hashtag profile pages, Wiki pages, any custom pages or directly to the tagged content via search. The output can be customized using flexible XSLT-based templates, static and dynamic (for larger taxonomies).
The Layer2 Tag Navigation Web Part goes far beyond the out-of-the-box metadata navigation features of Microsoft SharePoint Server 2010 and 2013, where pages can be assigned to each metadata item manually only. Please note, that a flat alphabetical (A-Z) Tag Directory Web Part is available as well.

The links can be customized to link to tag or hastag profile pages, Wiki pages, custom pages or directly to search for categorized content. No pages must be assigned to the terms manually.
