Here is the ng-bootstrap typeahead code:
<div class="col">
<input
id="typeahead-config"
type="text"
class="form-control"
[(ngModel)]="model"
[ngbTypeahead]="search"
formControlName="searchText"
[resultFormatter]="formatted"
[inputFormatter]="formatter"/>
</div>
How do make changes to this dropdown?
I need to add a custom<b>{{item.somevalue}}</b> tags to that dropdown. Thank you!

@skouch2022 is right.
