Is there a solution to the problem that the scroll bar on the left side of the modal box returns to the top when an item in the accordion is clicked?

Question

On the initial load, if I click on the "Sales" accordion and then click on "Reported and Forecasted Total Sales", the scroll bar for the marker will jump to the top

Answer 1

<div mat-dialog-content class="matContent" *ngIf="filter.filterGroupKey === 'drugReportedSalesAndForecastGroup'" preserve>
  </div>

Add preserve and check if it is valid
