Thanks so much for the help! Perhaps give me a bit more to go on? Is the default dropdown login info a module or object that can be moved as a whole? Any chance you'd be kind enough to provide an example?
While you may move it to anywhere, it depends on where exactly you are trying to do and where you want to move to. The user dropdown is supposed to be placed inside the top navbar, it is not suitable to move it to the side menu bar.
