Hi, I've been working with Ruby on Rails to make a web application, but I've found something that I really cannot work out how to do with it, so it may be best if I do it manually.

Basically, I've got a dropdown menu, that is populated with a list of projects. I want users to be able to select a project from that list, and then all the details appear below it in a table (2 rows, the headers and the info).

How would I acheive this with AJAX? Any help anyone could give would be great, thanks!
