How to restrict nested header tags

Me too, please help! I am getting this problem using the Styles DD Menu.

So I did notice a method to the madness of this issue.

As a user of any rich text document, we know that if you hit the B button for bold, the characters stay bold until you again click the B to turn off the boldface type. This is how the Style DD list works too. You have to do it systematically; select your style, type your text, then de-select the same style to turn it off. The closing tag will follow this action. Then you have to repeat to return to your original or other style.

This is not going to be good for my users. Since they do not know or care what HTML tags are (nor should they) and what is rendered looks OK to them, they will probably just go along and create ugly and possbily broken HTML

Maybe I can look into fixing it myself and pass the info along.
