Javascript isn't required but can be used to improve the user experience. For example, Superfish <http://users.tpg.com.au/j_birch/plugins/superfish/>has a mouseout delay, incorporates hoverIntent <http://cherne.net/brian/resources/jquery.hoverIntent.html>, and optionally includes Supersubs<http://users.tpg.com.au/j_birch/plugins/superfish/#sample5>for variable menu width. hoverIntent is particularly helpful with multi-level menus, as it allows you to jump diagonally down to an item in the expanded submenu rather than having to make a horizontal move followed by a vertical move (try that on the GRC menu and you'll see what I mean).
