Once enabled, this textformatter looks for iframe embed URLs and converts those to HTML <iframe> elements. Works best with RTE (CKEditor, TinyMCE) inputs.
Note that URLs need to be the only content within a paragraph tag. You can use an absolute URL or a relative URL, but in the case of relative URLs the path must point to a file within /site/assets/files/:
<!-- valid -->
<p>iframe/https://www.domain.tld/path/</p>
<p>iframe//site/assets/files/1/example.pdf</p>
<!-- invalid -->
<p>iframe/Dude, where's my https://www.domain.tld/car/</p>
<p>iframe/site/assets/files/1/example.pdf</p>
<p>iframe//some/other/path/example.pdf</p>Embed tag (default: iframe/) and iframe tag can be customized via module configuration settings. Default iframe tag is <iframe class="TextformatterIframeEmbed" src="{url}"></iframe>; {url} is used as a placeholder for the provided source URL.
