/* Dropdown (static/select.js) -- the one place its look is defined.
 *
 * Deliberately its own file, not part of style.css or cockpit.css: the component is shared by the
 * website and (once opted in) the console, and only its BOX chrome needs to match the surrounding
 * form. That chrome is copied from `.field select` in style.css, so an enhanced dropdown is
 * indistinguishable from a plain field until it is opened.
 *
 * The panel is absolutely positioned inside the wrapper: it therefore opens under the field, at the
 * field's width, on every browser -- which is the entire point (see select.js).
