ADDING MENU BLOCKS
To add new menu blocks, use the "Add menu block" link on the administer blocks
page, admin/structure/block. You will then be able to configure your menu block
before adding it.
CONFIGURING MENU BLOCKS
When adding or configuring a menu block, several configuration options are
For menu trees that start with the 1st level, the default block title will be
the menu name. For menu trees that start with the 2nd level or deeper, the
default block title will be the title for the parent menu item of the
For example, if the active menu trail for the Management menu is: Administer >
Structure > Menus > Main menu, then a menu block configured to start with the
1st level of the Management menu will display a block title of "Management".
And a menu block configured to start with the 3rd level of the Management menu
will display a block title of "Structure".
Block title as link
For menu trees that start with the 2nd level or deeper, the default block
title will be the title for the parent menu item of the specified level. If
this option is checked, the block title will be a link to that menu item.
To help identify the block on the administer blocks page, you can specify a
unique title to be used on that page. If blank, the regular title will be
Select the menu to use for the tree of links.
Blocks that start with the 1st level will always be visible. Blocks that start
with the 2nd level or deeper will only be visible when the trail to the active
menu item is in the block's tree.
From the starting level, specify the maximum depth of the tree. Blocks with a
maximum depth of 1 will just be a single un-nested list of links with none of
those links' children displayed.
Make the starting level follow the active menu item
If the active menu item is deeper than the level specified above, the starting
level will follow the active menu item. Otherwise, the starting level of the
tree will remain fixed.
All children of this menu will be expanded.
Sort each item in the active trail to the top of its level. When used on a
deep or wide menu tree, the active menu item's children will be easier to see
when the page is reloaded.
Fixed parent item
If you select a specific menu item, you alter the "starting level" and
"maximum depth" options to be relative to the fixed parent item. The tree of
links will only contain children of the selected parent item.
STYLING MENU BLOCKS
Themers should look at the myriad of classes added to the <div>, <li> and <a>
The <div> wrapped around the menu tree has a class for several of the
configurable options of the block: menu-block-[block id number]
menu-name-[menu name] parent-mlid-[menu link ID] menu-level-[level number]
The <li> elements of the menu tree can have an extended list of classes
(compared to standard menu trees): first last menu-mlid-[menu link ID]
has-children active active-trail
The <a> elements of the menu tree can have: active active-trail
In addition, the wrapper <div> for the block is generated using the
menu-block-wrapper.tpl.php template. And Menu block provides several theme hook
suggestions for that template:
- menu-block-wrapper--[block id number].tpl.php
- menu-block-wrapper--[menu name].tpl.php
For example, a file in your theme called
menu-block-wrapper--main-menu.tpl.php can be used to override the <div> for
just the "Primary links" menu blocks.
Menu block uses Drupal core's menu theme functions. However, it also provides
theme hook suggestions that can be used to override any of the theme functions
called by it.
- theme_menu_tree() can be overridden by creating one of:
- [theme]_menu_tree__[menu name]()
- [theme]_menu_tree__menu_block__[menu name]()
- [theme]_menu_tree__menu_block__[block id number]()
- theme_menu_link() can be overridden by creating one of:
- [theme]_menu_link__[menu name]()
- [theme]_menu_link__menu_block__[menu name]()
- [theme]_menu_link__menu_block__[block id number]()
For example, if you created a bartik_menu_tree__menu_block() function, it would
override theme_menu_tree() any time it was used by this module, but not when
used by any other module. Similarly, a bartik_menu_link__menu_block__1()
function would override theme_menu_link(), but only for the first menu block in
your system (the menu block with an ID of 1).
MENU BLOCK API
Developers can use the API of this module to create their own menu trees outside
the confines of blocks. All of the publicly available API functions are
documented in the menu_block.module file.
In addition, Menu block implements HOOK_menu_block_get_menus(),
HOOK_menu_block_get_sort_menus() and HOOK_menu_block_tree_alter(). See
menu_block.api.php for documentation.
