Button in Editor with select menu possible?

[Robert9]

I know that we can add more buttons to the editor. But can we add a button with a select menu like QUOTE, CODE (...) also?

Say i want to have three new bbcodes inserted in just the same way like QUOTE and CODE. (I dont want to know about other ways, please).
Is this possible on a secure way without changing the editor itself?

Thank you very much.
