So only use \' for attributes of the nested shortcode.<br><strong>BBCode:</strong> If you have special characters e.g. [] in the url you need to use the bbcode style for the url: [advanced_iframe]url[/advanced_iframe].<br><strong>PDF support: </strong>If you include a pdf google doc is used to render the pdf.

By default unknown attributes are ignored in the shortocde and even reported if you enable the short code validation. If you like to add e.g. data-custom="my-custom" to the iframe you can add e.g. custom="data-custom=\'my-custom\'" here. " needs to be repaced by \'. This is then replaced again when the attributer is rendered. Multiple attributes can be separated by a space. Shortcode attribute: custom=""', 'advanced-iframe'), 'text', 'https://www.tinywebgallery.com/blog/advanced-iframe/demo-advanced-iframe-2-0');
