How can we sort an array according to selected name

Question

Here is my data which i get from api. Just a sample data.

  Id   CategoryName   itemTitle   itemvalue
     1    General       Height         155
     2    Lipid         Cholestrol     25
     3.   NIBP          SBP             85

And here is the UI i have i wanted to put the General at the top of the list. I wanted to select it by name like "General" not by id because same id repeated at my data. So i cannot select it by Id to get the desired output.

And this is the html i have

 <mat-expansion-panel 
                  *ngFor="let hubxReport of hubxReportList | sort:'asc':'displayOrder'; let i=index" class="fontsize">
                  <mat-expansion-panel-header>
                    <mat-panel-title >
                      <h6 class="fontsize" >{{hubxReport.categoryName}}</h6>
                    </mat-panel-title>

                  </mat-expansion-panel-header>

                  <div class="row">
                    <div *ngFor="let item of hubxReport.hubxDataItems" class="col-sm-4">
                      <mat-form-field class="example-full-width lineheight25 fontsize">
                        <input
                          class="fontsize"
                          matInput
                          autofocus
                          placeholder="{{ item.itemTitle }}"
                         />
                         <ng-container [ngSwitch]="item.itemTitle" id="container">
                          
                          <img class="img thumbnail" (click)="openDialogImg(myTemplate)"
                            *ngSwitchCase="
                              ['Graph1', 'Graph2'].includes(item.itemTitle)
                                ? item.itemTitle
                                : !item.itemTitle
                            "
                            [src]="_sanitizer.bypassSecurityTrustResourceUrl(item.itemValue)"
                            [alt]="item.itemTitle"
                          /> 
                          <!-- this template is invisible. It will be shown in the popup -->
                         <ng-template #myTemplate>                          
                           <!-- this is a big popup image.  -->
                           <img [src]="_sanitizer.bypassSecurityTrustResourceUrl(item.itemValue)" style="height:100%; width:100%">
                           <button id = "x" mat-button (click)="myDialogRef?.close()">X</button>
                         </ng-template>                        
                          <span *ngSwitchDefault>{{ item.itemValue }}</span>
                        </ng-container>
                        &nbsp;
                        {{ item.itemUnit }}
                       
                      </mat-form-field>
                    </div>
                  </div>

So how can i achieve it. can we achieve it by using pipe. If there is best way to achieve it that will be helpfull.

To sort your array you can use something like String.prototype.localeCompare()

reports.sort((a, b) => a.categoryName.localeCompare(b.categoryName))
