Filtering of HTML

I am working on WYSIWYG editor for Zammad Knowledgebase and it seems like Zammad is filtering out <span> elements. Can anyone confirm and shed some light on where this happens / how it can be overridden?

This is done by Zammads Sanitizer.
Most of the relevant parts, in theory, life here:

however, please note that you should be super careful with adjusting this part of Zammad, because many sanitizings are there for specific reasons to ensure that your Zammad keeps on running.

Agreed! Sanitization is very important!

I found the configuration file which dictates what’s allowed, and I see that span and span>style>color is already whitelisted. So this example for red text should work, but the span tag gets stripped out; any ideas?

<div contenteditable="true" id="396033_translation::content::body" data-name="translation::content::body" class="richtext-content ">
<p><span style="color:red;">This is RED text!</span></p>

You’re proberbly looking at develop code. If you’re instance is using stable code (which I suggest to do!) it won’t work. Wait for the next Zammad release or switch to develop (not recommended)
