Chained Menu

[Exitilus]

I've spent the better part of a week looking for something to do this and can't.

I have two drop down menu's on a form. The menu's will not have a submit button for themselves, just hte global form submit i've placed at the bottom. The first menu is just a list of Categories. This info doesn't matter where it comes from. The 2nd menu is a list of things from in the categories selected, but it has to pull this stuff from a MYSQL database.

Everything I've found has either not worked, causes a refresh on the page which looses all the information put above this.

I've tried just about every script i can find from ajax to javascript and none of them will work or a coding nightmare

Any clues anyone ?
