 * Provides a simple "jump menu".
 *
 * A jump menu is a select box and an optional 'go' button which can be removed
 * if javascript is in use. Each item is keyed to the href that the button
 * should go to. With javascript, the page is immediately redirected. Without
 * javascript, the form is submitted and a drupal_goto() is given.

/**
 * Generate a jump menu form.
 *
 * This can either be used with drupal_get_form() or directly added to a
 * form. The button provides its own submit handler so by default, other
 * submit handlers will not be called.
 *
 * One note: Do not use #tree = TRUE or it will be unable to find the
 * proper value.
 *
 * @code
 * ctools_include('jump-menu');
 * $output = drupal_get_form('ctools_jump_menu', $targets, $options);
 * @endcode
 *
 * @param $select
 *   An array suitable for use as the #options. The keys will be the direct
 *   URLs that will be jumped to, so you absolutely must encode these using
 *   url() in order for them to work reliably.
 *
 * @param $options
 *   $options may be an array with the following options:
 *   - 'title': The text to display for the #title attribute.
 *   - 'description': The text to display for the #description attribute.
 *   - 'default_value': The text to display for the #default_value attribute.
 *   - 'hide': If TRUE the go button will be set to hide via javascript and
 *     will submit on change.
 *   - 'button': The text to display on the button.
 *   - 'image': If set, an image button will be used instead, and the image
 *     set to this.
 *   - 'inline': If set to TRUE (default) the display will be forced inline.
