Introducing Picklists

When viewing the preview of what we wanted our Positions page to ultimately look like, there were several fields that were specified with drop-down lists. In Lightning platform terms, these fields are called picklists, and they consist of several predefined options from which a user can select.

Picklists come in two flavors: a standard picklist, in which a user can select only one option, and a multi-select picklist, in which a user can select multiple options at a time. For the purposes of our Position object, we need to define standard picklists for a position's location, status, type of job, functional area, and job level.
