I want to display taxonomy terms list.
I have a taxonomy named "Categories", I want to make a views page where all terms displays which has no childs. If user clicks on any listed terms then next level of respective terms displays and so on. If a term doesn't have any child terms then it should displays post of related term. My content type posts will be attached to last level of taxonomy.
Is it possible using Drupal 7 Views? Help me please.
