choices configuration ​

The choices setting in checkboxes, radio, or select fields configures the options that a user will see in the interface and the values that the server will allow in validation. The choices value is an array of objects with label and value properties.

  • value is used in the field's database value
  • label is the more human-readable version used in interfaces

Populating choices dynamically ​

What if the choices aren't known in advance? Then you can fetch them dynamically.

First, set the choices option to the name of a method in your module. Pass a string, the name of the method you'll implement on the server side β€” do not pass a function.

Second, implement that method in your module so that it takes (req, data) arguments and return an array of choices in the usual format. You may use an async function, or return a promise that will resolve to the array. That means you can reach out to APIs using modules like axios or node-fetch, or make Apostrophe database queries.

The data argument is an object containing the parent's docId for further inspection by your function.

It is usually a good idea to perform at least short-term caching in your choices method, in order to limit the impact on performance when editing.

autocomplete ​

The string supplied to the autocomplete option is used as the value of the autocomplete attribute for the field, as specified in the HTML standards. This feature suggests possible values based on user inputs and previously entered data, streamlining data entry and improving form usability. This also takes a string of off to disable autocomplete for sensitive fields. For detailed information on how the autocomplete attribute works and the values it accepts, refer to the MDN documentation on autocomplete.

Use in templates ​

Select field data is stored as the string value property of the selected choice.
