In this stackblitz:

https://stackblitz.com/edit/angular-mat-select-multi-with-formcontrol-nfsokg?file=app%2Fselect-overview-example.html,app%2Fselect-overview-example.ts

The default settings of the check boxes for the entries “one”, “two”, “three”, “four”, “five” in the drop down are false, so all boxes are unchecked.

How can I two-way-data-bind these values to the variable “checks” in the ts file?:

checks: boolean[] = [true, true, false, false, true];
