Important Note Starting with Version 2.0.11

Starting with version 2.0.11, any HTML code present in the shortcode or block is filtered to prevent dangerous code (e.g. JavaScript) from being output.

However, if you want to allow certain tags or attributes as a deliberate choice:
In the plugin’s “Basic Settings” there is a field called “Allow additional HTML tags (advanced)”.
There you can enter comma-separated tags that should not be filtered out. For example, “iframe,script” would preserve these two tags in the HTML output.

“tr#onclick” would preserve the “onclick” attribute in ”<tr onclick=..>”, which would otherwise be removed.
