Question : Smart Forms...

I'm not a expert javascript programmer so I just know the basics but I was wondering if other programmers know of any simpler tools to show or hide certain form elements based off of a value of other form elements?

So for example if I select "Ad Banner" from a drop down below the the select menu with "Ad Banner" a file field will show up below the select menu. I remember their being something out there a while back that would trigger/show/hide

Put an id on the element to hide/show, and use

document.getElementById('ElementId').style.display = 'none';

...to hide it, and

document.getElementById('ElementId').style.display = '';

...to show it.
