How to use focus for ng-select in Angular 5 ?
<label class="input">
<input (blur)="goTo()" type="text">
</label>
<label class="select" >
<div *ngIf="items.length > 0" >
<ng-select #select [items]="items">
</ng-select>
</div>
</label>
#ViewChild('select') myElement: ElementRef;
goTo(){
this.myElement.element.nativeElement.focus();
}

Answer 1

this works fine for me,
#ViewChild('ngSelect') ngSelect: NgSelectComponent;
ngAfterViewInit() {
if (this.autofocus) {
setTimeout(() => {
this.ngSelect.focus();
});
}
}

Answer 2

Change this
goTo(){
this.myElement.element.nativeElement.focus();
}
to this,
import { ChangeDetectorRef } from '#angular/core';
constructor (private cRef: ChangeDetectorRef) {}
// import 'SelectComponent' from your library for 'ng2-select'
goTo(){
let el = null;
if (this.items.length > 0) {
this.cRef.detectChanges();
el = (this.myElement.nativeElement as SelectComponent).element.nativeElement.querySelector('div.ui-select-container > input');
if (el) { el.focus(); }
}
}
You may have to check if the element is defined or not (or if you need an extra 'nativeElement' in there, but I'm basically reusing the logic in here.
Just a cautionary note, this may not be a stable fix though if the library updates to rename these classes or modify the template.
Hope it helps.

A quick reply, in this solution,each select elements are recorded for future usage (and in this case , blur). This needs being adapted to your situation.
import { Component, OnInit } from '#angular/core';
import { ViewChildren, QueryList } from '#angular/core';
#Component({
selector: 'app-editor',
templateUrl: './editor.component.html',
styleUrls: ['./editor.component.css']
})
export class EditorComponent implements AfterViewInit {
// Viewchildren
// https://netbasal.com/understanding-viewchildren-contentchildren-and-querylist-in-angular-896b0c689f6e
myindex:number;
#ViewChildren("select") inputs: QueryList<any>
constructor() {
this.myindex=0
}
// You will have to setup some input parameters in this function in order to switch to the right "select", (you have control)
private goTo()
{
// focus next input field
if (this.myindex +1 < this.inputs.toArray().length)
{
this.inputs.toArray()[this.myindex +1].nativeElement.focus();
this.myindex = this.myindex + 1;
}
else {
this.inputs.toArray()[0].nativeElement.focus();
this.myindex = 0;
}
}
private processChildren(): void {
console.log('Processing children. Their count:', this.inputs.toArray().length)
}
ngAfterViewInit() {
console.log("AfterViewInit");
console.log(this.inputs);
this.inputs.forEach(input => console.log(input));
// susbcribe to inputs changes, each time an element is added (very optional feature ...)
this.inputs.changes.subscribe(_ =>
this.processChildren() // subsequent calls to processChildren
);
}
}

A Simple way, you can do this also.
<label class="input">
<input (blur)="goTo(select)" type="text">
</label>
<label class="select">
<div *ngIf="items.length > 0">
<ng-select #select [items]="items">
</ng-select>
</div>
</label>
And in Typescript File.
goTo(select){
select.focus();
}
