Are you looking for a way to add iFrames to the TinyMCE editor? While there’s probably a plugin for this, we have created a quick code snippet that you can use to support iFrames in editor in WordPress.
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
add_filter('tiny_mce_before_init', create_function( '$a','$a["extended_valid_elements"] = "iframe[id|class|title|style|align|frameborder|height|longdesc|marginheight|marginwidth|name|scrolling|src|width]"; return $a;') );
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.

FYI: this snippet, even once adapted as an anonymous function for PHP 7’s sake, breaks Classic Editor’s TinyMCE
Thanks for it while it lasted.
Is there a reason this isn’t part of the WP core?
You know to be honest I’m not sure,
