Overview

A select menu, just as with a standard HTML <select> tag, creates a drop down menu with a list of options for a user to choose. The select menu also includes type-ahead functionality, where a user can type a part or all of an option string to filter the list.

This select menu will load its options from an external data source, allowing for a dynamic list of options.

Each time a select menu of this type is opened or the user starts typing in the typeahead field, we’ll send a request to your specified URL. Your app should return an HTTP 200 OK response, along with an application/json post body with an object containing either an options array, or an option_groups array.
