Cripes! People are a bit slow today... what you are describing sounds like a hierselect to me: In pear,... http://pear.php.net/package/HTML_QuickForm/docs/3.2.1/HTML_QuickForm/_HTML_QuickForm-3.2.1_QuickForm_hierselect_php.html If you want to do it yourself just look at their code and get your inspiration from there - and yes, their solution is javascript based.
