Create two dynamic select lists Hi,
I want to create a drupal view that display as the uploaded image. There are two select list. First select list is static. According to the selected category sub category should by populated. All categories and subcategories are stored as taxonomy term. Any idea would be appeciated.
You can take a look at the Taxonomy menu module. Some details about it (from its project page):


  Transforms your taxonomy vocabularies into menus with ease!
  
  
  Custom Menu per vocabulary
  Uses the default taxonomy term path or custom paths
  Integrate with Views
  Integrate with Pathauto: use URL/path aliases
  Does not interfere with other menu modules
