How to create an iframe with html code coming from ACF

[WeLoVeBricKs]

use code block:

@timmse

What you can do instead is to use the code block and render the field with PHP (check the ACF documentation for more customization options):

<?php 
  $iframe = get_field('textarea'); //this is your acf field

  if($iframe) {
	  echo $iframe;
  }
?>

change “textarea” with your field name
