Hello,

We've currently been trying to import some HTML through the editor, but it keeps deleting parts of it. We can allow CSS classes through the admin panel, but we'd like to completely disable that feature so any code can be put in the editor without deletion. 

How can we do that and where?

Thanks

If your class names are unique it should work if I'm not mistaken but you would need to refer to class names existing in your templates .
