This is DropBar acting as a 2-level menu: move the mouse over any button (apart from 'Utilities') and a second level of buttons appears.

The 'Utilities' button is a link, and so is the 'Text' button, as well as all 2nd-level buttons. (Of course, we've disabled the links, so you can click without linking anywhere.)

The animation speed is set to 'Normal', and all button text is centered.
