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,
}
```

The Collapsible Field is presentational-only and only affects the Admin Panel. By using it, you can place fields within a nice layout component that can be collapsed / expanded.

|
To add a Collapsible Field, set the `type` to `collapsible` in your [Field Config](./overview):
|
|
|
|
```ts
|
|
import type { Field } from 'payload'
|
|
|
|
export const MyCollapsibleField: Field = {
|
|
// ...
|
|
// highlight-start
|
|
type: 'collapsible',
|
|
fields: [
|
|
// ...
|
|
],
|
|
// highlight-end
|
|
}
|
|
```
|
|
|
|
## Config Options
|
|
|
|
| Option | Description |
|
|
| --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
|
| **`label`** \* | A label to render within the header of the collapsible component. This can be a string, function or react component. Function/components receive `({ data, path })` as args. |
|
|
| **`fields`** \* | Array of field types to nest within this Collapsible. |
|
|
| **`admin`** | Admin-specific configuration. [More details](#admin-options). |
|
|
| **`custom`** | Extension point for adding custom data (e.g. for plugins) |
|
|
|
|
_\* An asterisk denotes that a property is required._
|
|
|
|
## Admin Options
|
|
|
|
To customize the appearance and behavior of the Collapsible Field in the [Admin Panel](../admin/overview), you can use the `admin` option:
|
|
|
|
```ts
|
|
import type { Field } from 'payload'
|
|
|
|
export const MyCollapsibleField: Field = {
|
|
// ...
|
|
admin: {
|
|
// highlight-line
|
|
// ...
|
|
},
|
|
}
|
|
```
|
|
|
|
The Collapsible Field inherits all of the default admin options from the base [Field Admin Config](./overview#admin-options), plus the following additional options:
|
|
|
|
| Option | Description |
|
|
| ------------------- | ------------------------------- |
|
|
| **`initCollapsed`** | Set the initial collapsed state |
|
|
|
|
## Example
|
|
|
|
`collections/ExampleCollection.ts`
|
|
|
|
```ts
|
|
import type { CollectionConfig } from 'payload'
|
|
|
|
export const ExampleCollection: CollectionConfig = {
|
|
slug: 'example-collection',
|
|
fields: [
|
|
{
|
|
label: ({ data }) => data?.title || 'Untitled',
|
|
type: 'collapsible', // required
|
|
fields: [
|
|
// required
|
|
{
|
|
name: 'title',
|
|
type: 'text',
|
|
required: true,
|
|
},
|
|
{
|
|
name: 'someTextField',
|
|
type: 'text',
|
|
required: true,
|
|
},
|
|
],
|
|
},
|
|
],
|
|
}
|
|
```
