Hi. I export theme for Drupal 7. Horizontal menu work OK, but vertical menu not. If I have submenu, I click on root item and I see small moving, but not expand subitems. If I setup on menu expand item, I see everytime expanded items. But I wish collapsed all and after click, expand subitems.

Can someone help me?
