CKEditor cuts my made-up tag?

Question

JavaScript

Sawed down a button that inserts

<continued_subscription>Продолжение за подписку</continued_subscription>

But the editor replaces this tag with .
I wrote CKEDITOR.config.allowedContent = true; but it did not help.
PS. Naturally, on the site at the output it will be cut out

Answer 1

Roughly speaking, you wrote "Yes" in the column "Acceptable content " . Actually it should look something like this:

allowedContent: 'a[!href]; ul; li{text-align}(someclass)'
