I have a list of items. I select one of the items. Then the second list is populated based on my selection of the item I selected in the first list.
We have implemented just such a solution for a client site and there are two ways of doing it: one is to load all the data on the first page request, then use Javascript to populate the second pulldown, when the first is changed. The second is to use XMLHttpRequest in Javascript, to send a second page request to the server and pull back the necessary data for the second pulldown. Either way, you'd be best to use Javascript, otherwise the whole page needs to be reloaded when the pulldown is changed (and you'd have to deal with other form field data going AWOL).
