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 => Rule.max(1)
}
You can also use
options to do some awesome stuff btw.
