Fast way to make all menu-links "Show as expanded"? Is there a way to automatically make all menu-links in all menus whatsoever "Show as expanded"? 

I have about 4 menus that contain many links and it's not serious to pass one by one and click "show as expanded".

Is there a module or a script that will do that automatically? Thanks,
Try using menu block and create block what level you want to trail you menu. You can also use menu expanded as per your requirement. Menu expanded is not well maintained.
