Is there a module similar to the Tiered Taxonomy Block module for Drupal 7? I have two taxonomies (tags, and group), and one content type (article). I want to show tags which have content in page of group/123.

I found Tiered Taxonomy Block which has similar functionality, but it is only for Drupal 6, at the moment.

What is a similar module for Drupal 7?
Not sure if there is a better solution but this can now be done in a round about way with views. 


Create a term view.
Add a required relationship to its parent term.
add a required relationship to node.
add term title for both term and parent term relationship and term count.


You'll have to display the hierarchy at the theme level unless you want to use group headers.
