Create a dropbutton menu.

Parameters

$title: The text to place in the clickable area to activate the dropbutton. This text is indented to -9999px by default.

$links: A list of links to provide within the dropbutton, suitable for use in via Drupal's theme('links').

$image: If true, the dropbutton link is an image and will not get extra decorations that a text dropbutton link will.

$class: An optional class to add to the dropbutton's container div to allow you to style a single dropbutton however you like without interfering with other dropbuttons.
