..translate sub-menus

Could you be more precise ? Without context it's hard to understand which sub menus you're talking about.

Since 1.3.4 version, a translation file is automatically generated for those submenus. However, since we had to change some strings to be compatible with joomla 1.6 some of the submenus won't be translated. In the mean time (after updating to the latest version and loading the new language files), you can edit the file administrator/language/sv-SE/sv-SE.com_hikashop.menu.ini to add them. Next version will properly handle all of them automatically.
