*
* label: The label that will be displayed alongside the field.
* placeholder: Optionally, you can display a placeholder value to be shown inside the field.
* type: The type of field. Options: text, checkbox, datepicker, editor, file, multi-checkbox, number, picture, radio, select, textarea, url
* priority: The priority of the field. This determines where in the form the field is displayed.
* value: The current/default value of the field.
* required: Whether the field is required. Set to `true` or `false`.
* data_type: How the field is saved in the database. The simplest option is to use `user` as in the example below, which will automatically save the field to the user meta table.
