I have an HTML embedded CDF on my website. The size that is actually being used up by the single manipulate in the CDF changes when you use the CDF; you can make more sliders appear, and then it will take up more space.
I have jQuery embedded in the page, so you can easily snoop around in the HTML DOM tree.
If you view the page in Firefox, and you got the Firebug extension, you can type in Firebug
$("embed").height() which will give you the result 400, which is the hardcoded value I gave for the height of the embedded CDF content. I can change that height later on, if I want to, for example
I'm actually pretty sure that it's impossible, but I would love to be proven wrong. Any ideas?
@Vitaliy: Thanks, I figured it out thanks to your comment, will post solution shortly.
