/**

|
* @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
|
||
