This sounds like a Javascript question, not a PHP question. Try asking in the Javascript forum.

Well it can only be done with Javascript. What you are attempting is a clientside behaviour. PHP is a serverside scripting language so cannot do that.

Or if you want a server-side solution, then you need to break it down into a series of separate forms: select an option on one form, click a "Next" submit button, and get the next form with options based on the prior form's selections. You can use session variables and/or hidden form fields to carry information from previous forms forward through the sequence.
