Taxonomy is a must have tool for grouping relevant content together. On the other hand, with the help of Views and exposed filter, user could easily list out the content with specific taxonomy.
Recently i found that there is a module which could turn the multiple levels taxonomy into multiple selection lists. It is called Hierarchical Select written by Wim Leers who is also the author of Drupal CDN module. Let’s try it now.
1. Download Hierarchical Select module and enable the Hierarchical Select Taxonomy.
3. Create a content type and add the Term reference to it, you can pick Hierarchical Select as widget.
4. You can configure the Hierarchical Select by clicking the Widget Type tab.
Looks cool, right? As i mentioned before, this Hierarchical Select could be applied to exposed filter too but this feature is not yet completely ported to Drupal 7. Thanks Wim Leers for his great work and i am looking forward to Views exposed filter integration.
