There are several ways of doing it and all involve javascript, some more than others. Here are some of the problems; . without javascript the only thing that will cause a form to be submitted to the server for rebuilding, is clicking a submit button. . with a minimal amount of javascript you can cause the form to be submitted to the server when an item is selected from the first pulldown box. . with javascript and javascript arrays, you can cause one list to "cascade" to the next without going to the server (maybe).
On your first list if you code something like the following; <select name="firstsel" onChange="this.form.submit();"> .... Note: the code inside the onChange quotes is actually javascript, but it is rather minimal, don't you think. When your form is submitted form variable "firstsel" will have a value, base on that you can send back to the browser the same form, with the firstsel list with one item selected, and the filled in second dependent list. This technique requires a round trip to the server and back for each selection and is not the best of user experiences, but sometimes it is all you can do. Javascript is not too painful, and I would encourage plagerism while you are learning it. You can eventually avoid sending the entire form to the server and retrieving an entire refresh of the page by using AJAX, but even there a round trip to the server is required (just not the entire form). You can find lots of useful scripts at http://www.hotscripts.com in their javascript section, a good place to see different techniques. Also Google can be your friend.
