Give us a better description, paste us the code of the iframe.

I have edited one from dynamicdrive for you, with the iframe code.


<script type="text/javascript">

/***********************************************
© Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
***********************************************/

//Input the IDs of the IFRAMES you wish to dynamically resize to match its content height:
//Separate each ID with a comma. Examples: ["myframe1", "myframe2"] or ["myframe"] or [] for none:
var iframeids=["dynamic-frame"]

//Should script hide iframe from browsers that don't support this script (non IE5+/NS6+ browsers. Recommended):
var iframehide="yes"

var getFFVersion=navigator.userAgent.substring(navigat or.userAgent.indexOf("Firefox")).split("/")[1]
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 16 : 0 //extra height in px to add to iframe in FireFox 1.0+ browsers

function resizeCaller() {
var dyniframe=new Array()
for (i=0; i<iframeids.length; i++){
if (document.getElementById)
resizeIframe(iframeids[i])
//reveal iframe for lower end browsers? (see var above):
if ((document.all || document.getElementById) && iframehide=="no"){
var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
tempobj.style.display="block"
}
}
}

function resizeIframe(frameid){
var currentfr=document.getElementById(frameid)
if (currentfr && !window.opera){
currentfr.style.display="block"
if (currentfr.contentDocument && currentfr.contentDocument.body.offsetHeight) //ns6 syntax
currentfr.height = currentfr.contentDocument.body.offsetHeight+FFextr aHeight;
else if (currentfr.Document && currentfr.Document.body.scrollHeight) //ie5+ syntax
currentfr.height = currentfr.Document.body.scrollHeight;
if (currentfr.addEventListener)
currentfr.addEventListener("load", readjustIframe, false)
else if (currentfr.attachEvent){
currentfr.detachEvent("onload", readjustIframe) // Bug fix line
currentfr.attachEvent("onload", readjustIframe)
}
}
}

function readjustIframe(loadevt) {
var crossevt=(window.event)? event : loadevt
var iframeroot=(crossevt.currentTarget)? crossevt.currentTarget : crossevt.srcElement
if (iframeroot)
resizeIframe(iframeroot.id);
}

function loadintoIframe(iframeid, url){
if (document.getElementById)
document.getElementById(iframeid).src=url
}

if (window.addEventListener)
window.addEventListener("load", resizeCaller, false)
else if (window.attachEvent)
window.attachEvent("onload", resizeCaller)
else
window.onload=resizeCaller

</script> - Don't ask me why I put it in a php thing.

Then the iframe..



<iframe id="dynamic-frame" name="dynamic-frame" src="some-page.php" scrolling="no" marginwidth="0" marginheight="0" frameborder="0" vspace="0" hspace="0" style="overflow:visible; width:100%; display:none"></iframe>


I can't remember if it use's ID or NAME, because the Dynamicdrive iframe pastey thing did not include it, I added the name bit, with both in place it should work.. Good luck!

Give the iframe these two variables: name="main" id="main"
Edit the width variable to whatever you want.
Use this code to make it expand, works in firefox, IE and much more:


<script type="text/javascript">
//<![CDATA[
window.onload = function() {
var f = document.getElementById("main");
function resize() {
var h = "";
var w = "";
if (f.contentDocument) {
h = f.contentDocument.documentElement.offsetHeight + 20 + "px";
// can't find anything for Opera and Firefox that works for the width. OffetWidth doesn't work right either.(f.contentDocument.documentElement,"").getPropertyValue("width");
} else if (f.contentWindow) {
h = f.contentWindow.document.body.scrollHeight + 5 + "px";
} else {
return;
}
f.setAttribute("height",h);
f.parentNode.setAttribute("height",h);
}
if (window.addEventListener) {
f.onload = resize;
} else if (f.attachEvent) {
f.attachEvent("onload", resize);
} else {
return;
}
resize();
}
//]]>
</script>Put it just before the </head> tag.

This code is useless if your layout isn't coded properly/in expandables (as is any other code to make the iframe expand, it either won't work or your layout will break when it expands).
