I am trying to disable ng-select through directive. Can anyone suggest How can I do this?

This is my code and here is the example. which was I trying.

setTimeout(() => {
  const selectElement = this.elementRef.nativeElement;
  if (this.elementRef.nativeElement.tagName === 'NG-SELECT') {
    console.log('selectElement :', this.elementRef.nativeElement);
    this.renderer.setProperty(selectElement, 'disabled', true);
    this.renderer.setProperty(selectElement, ' ng-select-disabled', '');
    this.renderer.addClass(selectElement, 'disabled');
    const inputEle = this.elementRef.nativeElement.querySelector('input');
    this.renderer.setProperty(inputEle, 'disabled', true);
  }
}, 1000); 

I tried many ways But I need to do this with directives Can anyone know how can i do this with directive?

  • [disabled]="true" => working with ngModel
  • [readonly]="true" => working with formControlName
  • But not working with directive.

Can anyone suggest how can I do this?

Working StackBlitz

just retrieve the host component from the constructor, so here NgSelectComponent and use the method setDisabledState

import { Directive, ElementRef, Renderer2 } from '@angular/core';
import { NgSelectComponent } from '@ng-select/ng-select';

@Directive({
  selector: '[appCurrencySelect]',
})
export class CurrencySelectDirective {
  constructor(private elementRef: ElementRef, private el: NgSelectComponent) {
    setTimeout(() => {
      const selectElement = this.elementRef.nativeElement;
      if (selectElement.nativeElement.tagName === 'NG-SELECT') {
        this.el.setDisabledState(true);
      }
    }, 1000);
  }

  ngAfterViewInit() {}
}
