Releases for DHTML Menu

This is primarily a bugfix release, though several translations were added.

Bugs
- Far too many issues to name: The latest hook_update_N had a NULL instead of an array() return value, causing countless people to see a completely meaningless type warning.
- #297536 while traversing the menu tree, an is_array check ensures that no type warnings are emitted.
- #356495: The tree-indexing now stores ancestor trails for each menu item, removing reliance on the stack from recursive calls to theme_menu_item_link and theme_menu_item. This reliance was breaking the module whenever the theme functions were called elsewhere, eg. by NiceMenu.

Translations
- Swedish translation updated
- Ukrainian translation added
- Dutch translation added
- #454700: Polish translation added

Bugs

- #355521: When multiple themes are used on one site (user-set, or admin theme) and at least one of them overrides theme_menu_item(_link), under certain conditions DHTML Menu would cause a fatal PHP error (or WSOD). DHTML Menu now keeps a separate record of the relevant theme functions for each theme.
- #337596: PHP warnings ("invalid argument for foreach") were generated under certain conditions due to insufficient data sanity checks. The variable is now ensured to be an array before calling foreach.
- #352005: Ubercart's Catalog links were made "unclickable" by DHTML Menu's Javascript. DHTML Menu now uses identifiers with "dhtml_menu" in their name to ensure uniqueness.
- #356231: When DHTML Menu is configured to allow only one open menu, and a site uses a zen-based theme based on an outdated version of zen (pre 6.x-1.x-beta3), there is a strange "shuttering" behavior where menus slide closed immediately after being opened. This is caused by the lack of a required CSS identifier in the printed markup. Although this is a bug in the affected themes, it is trivially avoided with one line in DHTML Menu.

Translations

- #349268, #345204: The German, Esperanto and Spanish locales were updated with the latest string additions (6.x-3.2) and received a plural syntax bugfix.

Two bugs were fixed in this release.

- #332100: Invalid markup generated: Duplicate ID attributes.
- #332156: static array needs to be initialized. (resulted in LOTS of warnings about a variable not being an array)

Finally after almost half a year of waiting, here is the new, all rewritten version 3.0 of DHTML Menu.

Significant Changes

Embracing the Menu System

DHTML Menu 5.x and 6.x-2.2 used the block system to override the static menu functionality. Version 3.0 ties directly into the menu system using the theme registry. The advantages of these are numerous, but the one you will most appreciate is that DHTML Menu now works with Book Navigation and any other module that works with menu trees.

Working out of the Box

A steady stream of questions and support requests used to be asked by people who simply couldn't turn on the module. The problem was that after enabling DHTML Menu, you still needed to work to get it functional - by replacing blocks, or changing their configuration in 6.x-1.04+. DHTML Menu will now by default be enabled for everything, until you disable it manually. The same applies to cloning menu items as page links - this is no longer an obscure feature configured with an explicit list of items, but globally enabled for all items, and switched on by default. Double-clicking is still around, but can be disabled now.

Numerous other small changes have been made...

Features

First version of DHTML Menu for Drupal 7. New features added:

#300106 Allow bullet icon to act as expander.
#273872 Choose animation effects and speed.

Also, several improvements in the Javascript and the settings UI.

Note: No upgrade path for settings yet. This module only stores a tiny amount of configuration data, but if you want to use it on a site upgraded from D6, you will need to set all configuration options again.

First Drupal 7 version of this module.

This version of DHTML Menu has been rewritten to use the theme_registy_alter hook, allowing it to hijack the themable functions of the Menu API rather than adding preprocessing functions for the blocks.

The module is much more flexible with this approach, which means that DHTML Menu now works with Book Navigation.

Furthermore, it has always been possible to "clone" menu items in such a way that while the item itself merely expands and collapses the submenu, the cloned item will link to the actual page. This setting has been a usability nightmare, because the user had to enter specially formatted text into a text area, essentially editing a raw settings file. The new version simplifies this by making it an all-or-nothing approach: All expandable menu items are either cloned or not. The cloning is also done in Javascript, which means that non-JS users are not confused by redundantly cloned links.

It is still possible to open a page directly by double-clicking on the item in question, but this can now be switched off, too. When the item cloning is disabled, it's not necessary.

This version is not yet being released for production use, to give the translators some time to submit new localizations.
