How to create 3 level drop down options in angular. We can make use of
angular-material?
[image: dropdown.PNG]
<h4>mat-select</h4>
<mat-form-field>
<mat-label>Pokemon</mat-label>
<mat-select [formControl]="pokemonControl">
<mat-option>-- None --</mat-option>
<mat-optgroup *ngFor="let group of pokemonGroups" [label]="group.name"
[disabled]="group.disabled">
<mat-option *ngFor="let pokemon of group.pokemon" [value]="pokemon.value">
{{pokemon.viewValue}}
</mat-option>
</mat-optgroup>
</mat-select>
</mat-form-field>
The above code has two level. But how can we make it to the 3 level.
Something like,
Label1 -> Option1 -> option1.1 and option1.2
Label1 -> Option2 -> option1.1 and option1.2
Label2 -> Option2 -> option1.1 and option1.2
