I have ng-select with list of values. If i click on selected value and click clear , need to set first option .Please help me how to sort it out . https://stackblitz.com/edit/ng-select-wdcg5a?file=app/app.component.ts
<ng-select class="" [items]="assigneeStatus" name="status_filter_id"
bindLabel="lookup_label" bindValue="com_lookup_id" placeholder="Assignee Status"
[(ngModel)]="searchAssigneeObj.status_filter_id" [hideSelected]="true"
#status_filter_id="ngModel">
<ng-template ng-label-tmp let-item="item">
<span>{{item.lookup_label || 'All'}}</span>
</ng-template>
<ng-template ng-option-tmp let-item="item" let-search="searchTerm"
let-index="index">
<span>{{item.lookup_label || ''}}</span>
</ng-template>
</ng-select>
There is no basic way to achieve this natively in ng-select.
You can define callback of (clear) event and add your first item in the array to achieve that goal.
HTML:
<ng-select [items]="cities3"
bindLabel="name"
multiple = true
placeholder="Select at least one city"
[(ngModel)]="selectedCities"
(clear)="clearSelect()">
<ng-template ng-label-tmp let-item="item">
<b>{{item.name}}</b> is cool
</ng-template>
<ng-template ng-option-tmp let-item="item" let-index="index">
<b>{{item.name}}</b>
</ng-template>
</ng-select>
TS:
export class AppComponent {
selectedCities = [];
cities3 = [
{
id: 0,
name: 'Vilnius',
},
{
id: 2,
name: 'Kaunas',
},
{
id: 3,
name: 'Pavilnys',
},
];
constructor() {}
addCustomUser = (term) => ({ id: term, name: term });
public clearSelect() {
this.selectedCities = [];
this.selectedCities.push({
id: 0,
name: 'Vilnius',
});
}
}
See the codes:
multiple: true -> stackblitz
multiple: false -> stackblitz
You can achieve this using clear method.
in your component add below code :
public selectedCity;
constructor() {
this.selectedCity = [this.cities3[0]];
}
then in the ng-select add clear event as below :
<ng-select
[items]="cities3"
bindLabel="name"
multiple = true
placeholder="Select city"
(clear)="resetCalculations();"
[(ngModel)]="selectedCity">
<ng-template ng-label-tmp let-item="item">
<b>{{item.name}}</b> is cool
</ng-template>
<ng-template ng-option-tmp let-item="item" let-index="index">
<b>{{item.name}}</b>
</ng-template>
</ng-select>
and then register the handler as below :
resetCalculations() {
this.selectedCity = [this.cities3[0]];
}
here is the working example : Working Demo
