Adjust weight for menu items in different languages
With Drupal 7 core alone, user-defined menu items are not translatable. The Menu translation module, part of the Internationalization (i18n) package, allows users to select a translation mode for each menu (Figure 1).

The following modes are available:


No Multilingual Options
Translate and Localize
Fixed Language




Translate and Localize Menus

For most use cases, and especially if the structure of your menus is consistent across languages, Translate and Localize is the preferred method of translating menus. You can create one menu for all languages, and translate or localize each menu item. There are two ways that menu items will be translated:


You can set a language when creating a custom menu item so that the
menu item will only show up for that language (Figure 1). Menu items
that link to nodes in a particular language will be treated this way.
You can localize other custom menu items without a language (for
example, menu items linking to Views pages). Use the Translate tab to
translate the menu item title and description (Figure 2). Translators
can also use the 'Translate interface' pages to translate these menu
items (Figure 3).

Fixed Language Menus

If you choose Fixed Language, you'll have to set up a separate menu in each language. This could become tedious if have a lot of languages enabled on your site, but is useful if the content or menu structure is different for each language.

Menu Items Linked to Nodes

Useful modules:


For Entity translation use entity_translation_i18n_menu submodule of
Entity translation.
For content translation use Menu translation - Node.


A menu item linked to a node will be displayed only when the node language matches the page language. This is due to how the menu system works and the 'Language selection' feature in i18n. Therefore, to get translated menus items that link to nodes, you first need translated content: see Translating content to different languages.
