- Step 2: Step 2: If you're using a newer version of Angular, make sure you've imported the forms module correctly. The forms module should be imported in the app.module.ts file, as shown above.
- Step 3: Step 3: After importing the forms module, try again to bind the ngModel directive to your input element.
Using Template-Driven Forms
