OneOf Option for Single Entry Field

4 replies

Last updated: Jul 26, 2022

Hi all. I was just thinking of something: while an

array

field has an option

of

to list all possible types to insert (either embed or reference), AFAIK there's no equivalent for a single entry field. For example, type

object

with

oneOf

. Something like this would be very useful to have IMHO:

{
  type: 'object',
  name: 'thing',
  title: 'Thing',
  oneOf: [{ type: 'widget'}, { type: 'tool' }]
}

Like a union type. I would love this.

You can use a selection of things though with an array and a validation of

maxLength

instead:

{
  type: 'array',
  name: 'thing',
  title: 'Thing',
  of: [{ type: 'widget'}, { type: 'tool' }],
  validation: Rule =&gt; Rule.max(1)
}

You can also use
options to do some awesome stuff btw.
