I have modal made of a search bar and a list of elements, created with a ngbDropdown splitted into 2 components, parent and child. It works correctly, but I can't figure out a way to enable navigation with keyboard (use UP & DOWN keys to move between list's elements).
Following the official documentation, I tried to use ngbDropdownItem, but it's not working.
These are my 2 component's templates:
<div ngbDropdown class="dropdown-no-arrow" (openChange)="openChange($event)" container="body">
<!-- trigger -->
<ng-container>
<button class="btn" ngbDropdownToggle *ngIf="authorizationService.loggedInUser">
<i class="fal fa-farm me-2"></i>
<span>{{ authorizationService.loggedInUser.name }}</span>
<i class="fal fa-chevron-down ms-2"></i>
</button>
</ng-container>
<!-- menu -->
<div ngbDropdownMenu aria-labelledby="currentMenuItem" id="currentDropdown_{{ id }}">
<button ngbDropdownItem (click)="openNewModal()">
<i class="fal fa-plus me-1"></i> <span i18n>New</span>
</button>
<dm-child-list [isListDisplayed]="isDropdownOpened"></dm-child-list>
</div>
</div><div class="dropdown-header d-flex margin-x align-items-center">
<h6 class=" mb-0 flex-grow-1" i18n>MY LIST</h6>
</div>
<div class="px-4 py-2">
<div class="form-group mb-0">
<input class="form-control form-control-sm" libAutofocus [(ngModel)]="elSearch" (ngModelChange)="elSearch$.next($event)" i18n-placeholder placeholder="Search elements">
</div>
</div>
<button *ngFor="let el of list; let i = index;" ngbDropdownItem [ngClass]="{'top-border': i === 0}">
<i class="me-2 fas fa-check-circle text-success"
*ngIf="selectedEl?.id === el.id" title="Current element"></i>
<i class="me-2 fal fa-circle" *ngIf="selectedEl?.id !== el.id"></i>
<span>{{ el.name }}</span>
</button>Can anyone help with making keyboard selection work?
Thanks!
