Ionic2, ion-select multiple - limit user selection

I'm new at Ionic2 and angular2.

I use ion-select plugin, and use multiple option. Is there any way to limit user selection, for example till three items?

unfortunately he doesn't have that kind of support. An alternative would be to add the maxlength directive stating the number of selected items desired. Thus, if a larger value is selected, the field will be invalid in the form.

you can use ionChange event in tempate:

<ion-select multiple="true" [(ngModel)]="selected_values"  (ionChange)="onSelect()">
                        </ion-select>

in ts:

selected_values=[];
onSelect(){
    if(this.selected_values.length==3){
        //do somthing
     }
}
