Then, when the user clicks on the link, your controller could gather the information submitted (such as what was selected) and redirect the browser to a new page which would present the same information plus either a text field or a text area. This has the benefit of simplicity and sticks with what you probably already know (hopefully), but it will be somewhat clunky and look different than the more modern way of doing what you describe. 2) The more modern way of doing what you describe is to use JavaScript and AJAX to dynamically render new portions of your page dependent upon what the user has entered so far. This has the benefit of looking very slick when done well, but requires that you learn something about JavaScript and AJAX. Fortunately, there are a lot of resources (in the form of web pages with tutorials as well as a plethora of books at your local technical bookstore). Hopefully, these couple of ideas will get you thinking in one direction or another. --wpd --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
