I am trying to build a nested Dropdown in angular.
In the latest versions of primeng, I could find the CascadeSelectModule that does exactly that. However, in my angular app, I am using a previous version of primeng : v11.4.5. I am also using angular v11.

Is it possible to create such a nested dropdown with the DropdownModule ? or to import a different module, that is available in primeng V11 ?

Thank you for your help

I created 2 dropdowns like this :

<p-dropdown *ngIf="region.title =='Hottest Lesion'" [ngStyle]="{'position': 'absolute'}"
                            [options]="bodyPartList" [(ngModel)]="location" [disabled]="disableForms" optionLabel="name"
                            (onChange)="bodyPartChange()" placeholder="Select Body Location" filter="true"
                            resetFilterOnHide="true" [contentStyle]="{'overflow':'visible'}">
                        </p-dropdown>
                        <p-dropdown *ngIf="region.title =='Hottest Lesion'" [ngStyle]="{'position': 'absolute'}" [hidden]="!subPartList.length"
                            [options]="subPartList" [(ngModel)]="sublocation" [disabled]="disableForms"
                            optionLabel="name" (onChange)="sublocationChange()" placeholder="Select Sublocation"
                            filter="true" resetFilterOnHide="true" [contentStyle]="{'overflow':'visible'}">
                        </p-dropdown>

The goal is to change it into a nested one.
