Tinymce On Addon Settings


I want to make my addon have an editor on the settings page, but I cant seem to find a way to do it. I set the input to textarea but doesnt have an editor on it. In a few words I want the client to be able to add some HTML code in it because the message is displayed on the front-end.

Thanks in advance.

Please use the template type of setting and add WYSIWYG editor there.
