Hi I read this article :- http://drupal.org/node/60530 and was able to follow it (using CCK and drupal 5.0). However I was unable to understand how to use it to do something like :- I have the categories / Subcategories as :- BOOK - Fiction - Non Fiction - Children - Programming CD - Movie - Educational Now while creating a view , how can I create 2 drop down lists, on one if I select BOOK the second should have the options as Fiction .... and if I select CD in the first drop down box , the second drop down should contain Movie etc ... I am using CCK to create my node types. (Basically I want to select the category from one drop down box and the subcategory from the other drop down list) Thanks and Regards Abhinav Drupal : Level : Novice
