{#
    /**
     * @file
     * Default theme implementation for a menu block.
     *
     * Available variables:
     * - plugin_id: The ID of the block implementation.
     * - label: The configured label of the block if visible.
     * - configuration: A list of the block's configuration values.
     *   - label: The configured label for the block.
     *   - label_display: The display settings for the label.
     *   - provider: The module or other provider that provided this block plugin.
     *   - Block plugin specific settings will also be stored here.
     * - in_preview: Whether the plugin is being rendered in preview mode.
     * - content: The content of this block.
     * - attributes: HTML attributes for the containing element.
     *   - id: A valid HTML ID and guaranteed unique.
     * - title_attributes: HTML attributes for the title element.
     * - content_attributes: HTML attributes for the content element.
     * - title_prefix: Additional output populated by modules, intended to be
     *   displayed in front of the main title tag that appears in the template.
     * - title_suffix: Additional output populated by modules, intended to be
     *   displayed after the main title tag that appears in the template.
     *
     * Headings should be used on navigation menus that consistently appear on
     * multiple pages. When this menu block's label is configured to not be
     * displayed, it is automatically made invisible using the 'visually-hidden' CSS
     * class, which still keeps it visible for screen-readers and assistive
     * technology. Headings allow screen-reader and keyboard only users to navigate
     * to or skip the links.
     * See http://juicystudio.com/article/screen-readers-display-none.php and
     * http://www.w3.org/TR/WCAG-TECHS/H42.html for more information.
