It is a common pattern to dynamically show and validate a select field's
options based on various criteria such as the current user or underlying
document.
Some examples of this might include:
- Restricting options based on a user's role, e.g. admin-only options
- Displaying different options based on the value of another field, e.g.
a city/state selector
While this is already possible to do with a custom `validate` function,
the user can still view and select the forbidden option...unless you
_also_ wired up a custom component.
Now, you can define `filterOptions` on select fields.
This behaves similarly to the existing `filterOptions` property on
relationship and upload fields, except the return value of this function
is simply an array of options, not a query constraint. The result of
this function will determine what is shown to the user and what is
validated on the server.
Here's an example:
```ts
{
name: 'select',
type: 'select',
options: [
{
label: 'One',
value: 'one',
},
{
label: 'Two',
value: 'two',
},
{
label: 'Three',
value: 'three',
},
],
filterOptions: ({ options, data }) =>
data.disallowOption1
? options.filter(
(option) => (typeof option === 'string' ? options : option.value) !== 'one',
)
: options,
}
```
Continuation of #10741. Field-level admin options, including the
conditional logic and custom field components, are currently documented
within the "admin > customizing views" page. This makes them hard to
find because users, myself included, intuitively navigate to the fields
overview doc first to locate this information. Now, they are rendered
within "fields > overview" as expected. This should help keep the user
from jumping around from doc to doc and getting lost.

`import type { Field } from 'payload/types'`
to
`import type { Field } from 'payload'`
2
`import { buildConfig } from 'payload/config'`
to
`import { buildConfig } from 'payload'`
3
```
import { SelectInput, useField } from 'payload/components/forms';
import { useAuth } from 'payload/components/utilities';
```
to
`import { SelectInput, useAuth, useField } from '@payloadcms/ui'`
4
uses `import type` for `import type { CollectionConfig } from 'payload'`
* chore: ensures example configs are being exported when necessary
* chore: adds note regarding updating of hidden fields
