Hi, on to the final bit of my blogging engine and would really appreciate a pointer in the right direction. With each article they can be associated with multiple categories, so inside the admin panel I need to somehow have a listbox that allows users to select multiple categories and associated them to an article. Now I can return an object of all the categories available and one that contains all the categories the current article is associated, putting that in a listbox and making it save the results is what stumps me. any ideas?

select_tag “article[category_ids]“, options_from_collection_for_select(@available_categories, “id”, “name”), :multiple=>true That should create a select box with multiple selected elements...
