Multi Select loading data about coreui-angular

[32x0lf]

Hi @xidedix ,

yes I tried but I encounter some issue where I initialize the fromcontrol. When I tried to search and select in the dropdown, it will reset to the initialize value. This only happens when you search in dropdown.

this.clienttForm = new FormGroup({
      accountmanager: new FormControl<string[]>(['0']),
    })

<c-multi-select
                    (searchValueChange)="searchValueChannelManager$.next($event)"
                    [options]="(optionschannelmanager$ | async) ?? []"
                    [search]="searchFn"
                    formControlName="accountmanager"
                    itemMinWidth="333"
                    single
                    virtualScroller
                    visibleItems="8"
                    size="sm"
></c-multi-select>

If I remove the default value and search in drop down,it will properly display the selected one

Thank you @xidedix

@32x0lf We are aware of the issue. Multi-select was not designed for such amounts of data.
We're going to introduce a virtual scroll for multi-select later this month to handle this use case.

@xidedix,

Is there a way that the data will populate right away during loading? it seems it will still wait for a couple of minutes. I tried another library which is ng-multiselect-dropdown it will populate right away but the problem is, the dropdown is being cut off from the parent component where the dropdown is placed and that component is the coreui accordion.

@32x0lf have you tried it with virtual scroller?
the example takes 10000 options without issues or delays
