Sorting reference field dropdown in Sanity

Sanity is a highly customizable headless CMS, where schemas are defined using code.

A field for referencing other documents can be defined like this:

fields: [
  defineField({
    title: 'Fruit',
    name: 'fruit',
    type: 'reference',
    to: [{type: 'fruit'}],
  }),
],

And looks like this:

...pretty nice. But it would look better if we could sort the fruit alphabetically. According to the documentation, it does not seem like that is possible, but way down in a github issue, there lies the solution.

Sorting is undocumented, but as easy as this.

fields: [
  defineField({
    title: 'Fruit',
    name: 'fruit',
    type: 'reference',
    to: [{type: 'fruit'}],
    options: {
      sort: [{field: 'name', direction: 'asc'}],
    },
  }),
],

Finally sorted:

That's it!
