/**
 * @file
 * Provide a javascript based dropdown menu.
 *
 * An example are the dropdown settings in the panels ui, like for adding
 * new panes.
 *
 * The dropdown menu will show up as a clickable link; when clicked,
 * a small menu will slide down beneath it, showing the list of links.
 *
 * The dropdown will stay open until either the user has moved the mouse
 * away from the box for > .5 seconds, or can be immediately closed by
 * clicking the link again. The code is smart enough that if the mouse
 * moves away and then back within the .5 second window, it will not
 * re-close.
 *
 * Multiple dropdowns can be placed per page.
 *
 * If the user does not have javascript enabled, the link will not appear,
 * and instead by default the list of links will appear as a normal inline
 * list.
 *
 * The menu is heavily styled by default, and to make it look different
 * will require a little bit of CSS. You can apply your own class to the
 * dropdown to help ensure that your CSS can override the dropdown's CSS.
 *
 * In particular, the text, link, background and border colors may need to
 * be changed. Please see dropdown.css for information about the existing
 * styling.
