  Hi @astrea

  Could you share how you are creating the dynamic items ? Are they loaded in cshtml or via JavaScript ? It would be great if you can share the related code as well.

  I assume, you are calling MenuComponent.reinitialization(); before the items are loaded like you said.

  Hi @ismcagdas,

  Let me try to provide the relavant code. I cut as much irrelevant stuff as possible

  lab-details.component.html

  <div [class]="containerClass">
      <div class="row">
          <div class="col-xl-6" *ngFor="let vm of labViewModel?.virtualMachinesViewModels">
              <div class="card mb-7 edulab-vm">
                  <div class="card-footer text-end">
                      <div class="d-flex flex-stack">
                          <div>
                              <button type="button" class="btn btn-sm btn-active-light-primary me-2" data-kt-menu-trigger="click">
                                BBB2
                              </button>
                            
                              <div class="menu menu-sub menu-sub-lg-down-accordion menu-sub-lg-dropdown menu-rounded-0 py-lg-4 w-lg-225px" data-kt-menu="true">
                                <div class="menu-item px-3">
                                  <span class="menu-link py-3">
                                    </span>
                                      <span class="menu-title" data-link="#">Some menu title</span>
  </div></div></div></div></div></div></div></div></div>
  

  lab-details.component.ts

  private refreshVirtualApplicationStatusTimer: Observable<number> = timer(0, this.refreshVirtualApplicationStatusIntervalSeconds * 1000);

              });
      });
  }
  
  private async loadVirtualApplication(vappId: string): Promise<LabInstanceDto> {

  Hi,

  So, where do you set labViewModel or labViewModel.virtualMachinesViewModels ? As an option, does taht work if you wrap MenuComponent.reinitialization with a setTimeout function ?

  Thank you for the tip! Wrapping the function in the setTimeout solved the problem! Also needed to move the refreshMenu function to the labViewModel.

  Kind Regards, Matt
