How to Remove or delete item from Array on change in Angular

Question

Here I want to remove selected item from array when I changed dropdown. I have few item in checkbox list and onselect I am pushing item in array but when I change dropdown then selected item should be removed from array. I have reproduced my issue on here,Please have a look on this link https://stackblitz.com/edit/angular-rhkz6i?file=src%2Fapp%2Fapp.component.ts

so after resetting the selectedGroups on changing the option, do you want to get get the selected checkboxes back once you re-select the same option. ? — Ashish Ranjan

You can just add this.selectedGroups = []; in your setGroup function so it can be reset

setGroup(nav:any, index){this.selectedGroups = [];}

I think you just want to reset this.selectedGroups. So inside setGroup(nav:any, index), add a line with this.selectedGroups = []
