I am trying to do a product review site with Drupal, I managed to work with views, fivestars but am confused. I want to have logged on users to be able to post reviews to already existing products or create a review for a new one. To do this I want my user to go let's say to electronics page and click post a review and in doing this he gets to write the review, choose category under electronics (let's say TV) and choose LCD under that. What I was able to do is put is put vocabulary (Electronics) under taxonomy and add terms (TV, LCD, etc ..). The problem is that this way I will have several vocabularies and the user has to choose from a long list which seems counter intuitive. I just want the categories under whatever section to show only things related to that section. I hope I explained it well and that you can help me guys with this. I have managed to create a menu on top with nice menus and in order to link it to nodes for categories (taxonomy), I used the /taxonomy/123 to point to each category page and in this page I want to be able see a link to add review under this category directly and not see the whole list of categories. I also created new content type called review and add taxonomy vocabulary to it using hierarchical taxonomy module.
