In tumblr, show only posts with a certain tag in the home page

Question

In tumblr, is it possible to show only posts with a certain tag in the home page?
If so, how is it done?

Answer 1

Tumblr’s Custom Themes don’t provide such a functionality.

You could use JS or CSS to (visually) hide all posts without a specific tag on the index page, but that way you won’t have the full 10 (or whatever you configured) posts per page anymore.

You could probably use Tumblr’s API to create a list of matching posts (with Javascript) and display that content instead of the default posts (so your custom theme would only contain the script for the index page content). You would have to make sure that the pager still works, though.
