<p-panel header="..." [toggleable] = "true" >
    <ng-template pTemplate="icons">
        <button
            pButton

            icon="..."
      (click)="menu.toggle($event)"
    </button>
    >

    <p-menu #menu [model] = "gfg"[popup] = "true" ></p - menu >
  </ng - template >
    <p>....</p>
</p - panel >
