點擊手風琴內的項目時，模態框左側滾動條返回頂部的問題有解決方案嗎？

Question

在初始加載中，如果我單擊“銷售”手風琴，然後單擊“報告和預測的總銷售額”，標記的滾動條將跳到頂部

標記的 ng-container 用於報告和預測總銷售額 UI

以下是總報告和預測銷售 UI 的 HTML

Answer 1

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

新增preserve並檢查是否有效
