thanks template... here plunker code http://plnkr.co/edit/r6bnadu124qoohjuwumz?p=preview

you doing right. there bug in angular2-mdl: open menu not closed if menu opened (just created: https://github.com/mseemann/angular2-mdl/issues/200).

the workaround until fixed: register click event listener on every button opens menu:

<button mdl-button (click)="hideallexcept(submenu)" class="mdl-navigation__link" #{{link.name}}="mdlbutton"  [mdl-toggle-menu]="submenu">{{link.name}}</button>

query in app component menucomponents:

@viewchildren(mdlmenucomponent) private menucomponents: querylist<mdlmenucomponent>;

and hide menus except 1 opened:

  hideallexcept(submenu) {    this.menucomponents.foreach( (menu) => {      if (submenu !== menu) {        menu.hide();      }    });   }
