                     </ul>
                  </li>
               </ul>
            </div>
            <ul class="megamenu-section">
               <li class="menu-section-title" id="menu-section-title-348">
                  <a href="/schengen">О Шенген-визах</a>
         </div>
         <div class="closepanel"><span class="close-panel" title="close this panel">close this panel</span></div>
      </div>
      </li></ul>    
</div>
<!--end main menu-->

I think the problem in incorrect of HTML code...

I found CSS solution
Need to add folowing code to primary-links.css file

.megamenu-section
{
	float: left;
}
