allow <iframe> HTML tag into the popup

Idea created by JoseMHeras on Mar 30, 2017

    I'd like to show contents form another source. For example, my own server. So I could call the content as:


    <iframe src='http://myserver/mypage.php?id={OBJECTID}>


    in my personalised popup window.


    I know about this idea:

    Allow raw HTML in arcgisonline popup configuration 

    But it doesn't work the <iframe> feature.


    Thank you very much.
