How do I link to tags in the navigation?
Tagging posts is Tumblr’s way of categorising content. You can link to tag pages in the navigation by creating a custom link.
All of our themes support custom links in the navigation in the form of Tumblr redirects.
An example of a tag page would be – yourblog.tumblr.com/tagged/YOURTAG
To insert a custom link, go to the customization panel for your blog, scroll to the bottom and hit “Add a page”, then choose “Redirect” from the options. Fill out the fields.
Please note this option may not show when you’ve created a new Tumblr account. You may have to wait a few days for it to appear.
