Enhancing the Simple App with Advanced Fields, Data Validation, and Page Layouts

In the last chapter, we got our Recruiting app off to a quick start by defining the Position custom object, tab, and several simple fields. This simple version of our app had the same look and feel as any other page on the Lightning platform, and we were able to whip it together in a matter of minutes.

In this chapter, we're going to enhance the Positions tab: first by defining a few more advanced fields, then by defining a couple of validation rules to make sure our data stays clean, and finally by moving our fields around within a page layout. These additions will help change the detail page of our Positions tab from a somewhat flat and inelegant user interface to something that users find powerful and intuitive to use. Let's get started!
