       <div style="display: none;">
         <input type="text">
       </div>
     
       <ng-select [items]="exportPdfInstance.tpaDetails" ngDefaultControl [virtualScroll]="true" bindLabel="tpaName"
         bindValue="tpaId" (change)="changeLeagueOwner($event)" placeholder="Select Tpa" formControlName="tpa">
       </ng-select>
     </div>
     <div class="group_item p-relative d-grid">
       <label>Program</label>

       <ng-select [items]="exportPdfInstance.detailsProgram" ngDefaultControl [virtualScroll]="true"
         bindLabel="clientName" bindValue="programId" placeholder="Select Program" formControlName="program">
