    Add hidden fields to a Form with Angular Formly


    Sometimes you need add values to your form without having a visible UI form control. A typical example is the id property of your data model. With Formly you actually have multiple choices. By default Formly has a 2-way databinding between the form and the data model. As a result you can directly use the model and send it back to the server as it will be always in sync with the form. If you decide to still use the form value, check out this lesson to see how to implement "hidden fields".
