Hi Sivad,

It is possible by pasting this script on your footer:


var iframes= document.querySelectorAll("iframe"); //get all iframes
iframes.forEach(function f1(elem){ //loop into each iframe

elem.addEventListener("load", function f2(){ //check if each iframe has 'loaded'

elem.style.height =elem.contentWindow.document.body.scrollHeight + 'px'; //assign the height

//if you want to add more to the height, you can do
//elem.contentWindow.document.body.scrollHeight + NUMBER + 'px';




If you want to do this on only one iframe when you have multiple:

1.) Assign an ID to the iframe, i.e. id="target"
2.)Use the following script



var iframe1 = document.getElementById("target"); //get iframe with id="target"
iframe1.addEventListener("load", function tx(){

iframe1.style.height =iframe1.contentWindow.document.body.scrollHeight + 'px';


Please note that this code will not work with a SEARCH FORM as it only resizes WHEN the contents of the iframe have been loaded.


Hope this helps.
