Currently I want to use the primeng autocomplete multi select component: https://www.primefaces.org/primeng/#/autocomplete
What I need additionally is that every item which I want to select from as an autosuggestion should be colored differently.
E.g. If I have the options Paris (red), Munich (blue) the background should be shown in a different color.
Once you have assigned a colour for each of your countries, just use templating to apply it :
<p-autoComplete [(ngModel)]="country" [suggestions]="filteredCountriesSingle" (completeMethod)="filterCountrySingle($event)"
field="name" [size]="30" placeholder="Countries" [minLength]="1">
<ng-template let-country pTemplate="item">
<div class="ui-helper-clearfix" [ngStyle]="{'background-color':country.backgroundColor}">
{{country.name}}
</div>
</ng-template>
</p-autoComplete>
Check my Plunker where I defined a random colour for each country :
this.listOfCountries.forEach(function (item) {
item.backgroundColor = "#"+((1<<24)*Math.random()|0).toString(16);
});
