By default, the Brilliant Directories platform supports iframes from YouTube, Vimeo, Facebook, and SoundCloud. Any other websites that provide sharable content through iframes are blocked, for security purposes, by Brilliant Directories.
However, you can bypass this security precaution by adding a comma-separated list of URLs that provide iframe content, to the Advanced Setting: iframe_source_whitelist
Once the URL of the website providing the iframe has been added, the iframe content should immediately display after it has been published on your website.
Important Note: Sharing content through whitelisted iframe sources will be supported by all Froala text editors on your website.
