How to select radio button and then show more options?

[BaseballGraphs]

Hello,

I was hoping someone could provide or suggest a resource where I may be able to see implementation of the following programming situation.

I would like to create a simple radio button form. I would like it when a user clicks a radio button for the form to show more options that are related to that radio button and only that radio button.

For example, if I have a form with two possibilities:
[] Right
[] Left

If someone clicks on the radio button for 'Right' I would like two more options to show up below this selection where the user is able to make another selection:
[x] Right

[] Option1
[] Option2

[]Left

Then, I am looking for a way to store all of the user's selections in a mySQL database.

If someone can provide some sort of guidance, example, resource, or idea on how to implement this type of programming problem I would be greatly appreciative!

Thanks!

Looks like a tree-style setup. There are several ways you could accomplish this. This is mostly a design question, if you ask me, but there is a programming aspect to it.

First, you could catch the onclick event for the radio button and call some AJAX to fetch more information from the server.

You could also set up a series of arrays and use them to drive the tree.

AJAX would probably be easier, just catch the onclick event and make a call to a PHP page that gets or calculates the next set of options for a user to select, based on what they already selected.
