How To Highlight The Option Selected In And Tag In Angular 5

I have 2 tags, when I click on the drop panel it gives various options to select, by default one value is selected but when I open the drop panel it is not highlighting the previou

Solution 1:

The definition of the select should be like this:

<ng-select
  [items]="filterJSONData"
  bindLabel="{{content}}" bindValue="{{val}}"
  [(ngModel)]="filterSelected">
  <ng-template ng-option-tmp let-item="item" let-search="searchTerm">
    <div [ngOptionHighlight]="search">{{ item.content }}</div>
  </ng-template>
</ng-select>

When you type a text in the select, the matches values are displayed underline.
