Usage

Like described above, the ngx-dawa-autocomplete is a module with a directive, that you can apply to any input/textarea element in your Angular application. Its built in a way so you have full control over the layout and structure of the autocomplete container, therefor its not a component.

First include the DawaAutocompleteModule in your module (main or sub)

import { NgModule } from '@angular/core';
 
import { DawaAutocompleteModule } from 'ngx-dawa-autocomplete';
 
import { AppComponent }  from './app.component';
 
@NgModule({
  imports: [
    BrowserModule,
    DawaAutocompleteModule.forRoot()
  ],
  declarations: [
    AppComponent
  ],
  bootstrap: [
    AppComponent
  ]
})
export class AppModule { }

then you apply the ngxDawaAutocomplete directive to the specified input element, and the rest of the html is what ever you decide.

import { Component } from '@angular/core';
import { DawaAutocompleteItem } from 'ngx-dawa-autocomplete';
 
@Component({
    selector: 'app',
    template: `
        <div class="autocomplete-container">
            <input
                type="text"
                [value]="selectedStreet"
                ngxDawaAutocomplete
                (items$)="onItems($event)"
                (highlighted$)="onItemHighlighted($event)"
                (select$)="onItemSelected($event)" />
            <ul class="autocomplete-items" *ngIf="items.length > 0">
                <li class="autocomplete-item"
                    *ngFor="let item of items; let i = index;"
                    [class.highlighted]="i === highlightedIndex"
                    (click)="onItemSelected(item)">
                    {{item.text}}
                </li>
            </ul>
        </div>
    `
})
export class AppComponent {
 
    public items: DawaAutocompleteItem[] = [];
    public highlightedIndex: number = 0;
    public selectedItem: DawaAutocompleteItem;
 
    public onItems(items) {
        this.items = items;
    }
 
    public onItemHighlighted(index) {
        this.highlightedIndex = index;
    }
 
    public onItemSelected(item) {
        this.items = [];
        this.highlightedIndex = 0;
        this.selectedItem = item;
    }
}
