Here's my code, I am just a beginner in the front-end world so please help me out to solve my delay issue in opening and closing the sidebar.

<mat-drawer-container autosize>
  <mat-drawer #drawer mode="side" [opened]="isShowing" (mouseout)="toggle()">
    <mat-nav-list>
      <div>
        <div>
          <a mat-list-item class="panel-list-item">
            Marketplace
          </a>
        </div>
      </div>
    </mat-nav-list>
  </mat-drawer>
  </mat-drawer-container>
