In this tutorial, I am gonna discuss that how we can create cascade dropdowns using arrays in angular.

Step1: First I will create a model.ts file to declare and define the model for program

In this model, I have created two model classes, first Department class is dedicated for department dropdown and second one employee class for second drop-down control. This task will be done just like primary and foreign key relationships in which id is working as a primary key and did is working as foreign key.

imports: [
