export class MyClass implements OnInit {
optionsModel: number[];
myOptions: IMultiSelectOption[];
ngOnInit() {
this.myOptions = [
{ id: 1, name: 'Option 1' },
{ id: 2, name: 'Option 2' },
];
}
onChange() {
console.log(this.optionsModel);
}
}In your template, use the component directive:
<ss-multiselect-dropdown [options]="myOptions" [(ngModel)]="optionsModel" (ngModelChange)="onChange($event)"></ss-multiselect-dropdown>Import the IMultiSelectOption and IMultiSelectTexts interfaces to enable/override settings and text strings:
// Default selection
optionsModel: number[] = [1, 2];
// Settings configuration
mySettings: IMultiSelectSettings = {
enableSearch: true,
checkedStyle: 'fontawesome',
buttonClasses: 'btn btn-default btn-block',
dynamicTitleMaxItems: 3,
displayAllSelectedText: true
};
// Text configuration
myTexts: IMultiSelectTexts = {

Although this dropdown is designed for multiple selections, a common request is to only allow a single selection without requiring the user to unselect their previous selection each time. This can be accomplished by setting selectionLimit to 1 and autoUnselect to true.
