Hi,

How can I add to editor possibility of use HTML?

There is a button to open the HTML mode. Also make sure that the HTML commands you want to use are set under Options > Gallery > Allowed Tags.

I found a solution. Check Your code for this and look for sanitize parameter. It clean as first state of cleaning, so that removes all tags. I dump it, and it return all good string, but did not save to database.

It is working perfectly for me and is not related to the sanitize parameter. I assume you did not what I told you...
