Hi All.

Does anyone know of any good tutorials that show how to piece together a form that changes as you select certain options? Or a decent (read "affordable") commercial form system that does this?

If you choose one option from a drop-down, the next drop-down changes in context. Or choosing an option from a select list reveals a new set of choices altogether.

Checkboxes used to hide or show form layers ("Use same information?" Yes being the default, a "No" or check off in the box would reveal a section to add new or different information.

Similar to the sitepoint order form, but more flexible.

Then the next part of the problem would be to get all the option data from a MySQL table to populate the form fields in the first place, so you wouldn't have to hard code the whole thing. Or would hard coding it be better/easier?
