Customizing Fields

Fields within the Admin Panel can be endlessly customized in their appearance and behavior without affecting their underlying data structure. Fields are designed to withstand heavy modification or even complete replacement through the use of Custom Field Components, Conditional Logic, Custom Validations, and more.

For example, your app might need to render a specific interface that Payload does not inherently support, such as a color picker. To do this, you could replace the default Text Field input with your own user-friendly component that formats the data into a valid color value.

Admin Options

You can customize the appearance and behavior of fields within the Admin Panel through the admin property of any Field Config:

1
import type { CollectionConfig } from 'payload'
2
3
export const CollectionConfig: CollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
name: 'myField',
9
type: 'text',
10
admin: {
11
// ...
12
},
13
}
14
]
15
}

The following options are available:

OptionDescription
conditionProgrammatically show / hide fields based on other fields. More details.
componentsAll Field Components can be swapped out for Custom Components that you define. More details.
descriptionHelper text to display alongside the field to provide more information for the editor. More details.
positionSpecify if the field should be rendered in the sidebar by defining position: 'sidebar'.
widthRestrict the width of a field. You can pass any string-based value here, be it pixels, percentages, etc. This property is especially useful when fields are nested within a Row type where they can be organized horizontally.
styleCSS Properties to inject into the root element of the field.
classNameAttach a CSS class attribute to the root DOM element of a field.
readOnlySetting a field to readOnly has no effect on the API whatsoever but disables the admin component's editability to prevent editors from modifying the field's value.
disabledIf a field is disabled, it is completely omitted from the Admin Panel.
disableBulkEditSet disableBulkEdit to true to prevent fields from appearing in the select options when making edits for multiple documents.
disableListColumnSet disableListColumn to true to prevent fields from appearing in the list view column selector.
disableListFilterSet disableListFilter to true to prevent fields from appearing in the list view filter options.
hiddenWill transform the field into a hidden input type. Its value will still submit with requests in the Admin Panel, but the field itself will not be visible to editors.

Field Components

Within the Admin Panel, fields are rendered in three distinct places:

  • Field - The actual form field rendered in the Edit View.
  • Cell - The table cell component rendered in the List View.
  • Filter - The filter component rendered in the List View.

To easily swap in Field Components with your own, use the admin.components property in your Field Config:

1
import type { CollectionConfig } from 'payload'
2
3
export const CollectionConfig: CollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
// ...
9
admin: {
10
components: {
11
// ...
12
},
13
},
14
}
15
]
16
}

The following options are available:

ComponentDescription
FieldThe form field rendered of the Edit View. More details.
CellThe table cell rendered of the List View. More details.
FilterThe filter component rendered in the List View. More details.
LabelOverride the default Label of the Field Component. More details.
ErrorOverride the default Error of the Field Component. More details.
DescriptionOverride the default Description of the Field Component. More details.
beforeInputAn array of elements that will be added before the input of the Field Component. More details.
afterInputAn array of elements that will be added after the input of the Field Component. More details.

* beforeInput and afterInput are only supported in fields that do not contain other fields, such as Text, and Textarea.

The Field Component

The Field Component is the actual form field rendered in the Edit View. This is the input that user's will interact with when editing a document.

To easily swap in your own Field Component, use the admin.components.Field property in your Field Config:

1
import type { CollectionConfig } from 'payload'
2
3
export const CollectionConfig: CollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
// ...
9
admin: {
10
components: {
11
Field: '/path/to/MyFieldComponent',
12
},
13
},
14
}
15
]
16
}

For details on how to build Custom Components, see Building Custom Components.

All Field Components receive the following props:

PropertyDescription
docPreferencesAn object that contains the Preferences for the document.
fieldThe field's config. More details
localeThe locale of the field. More details.
readOnlyA boolean value that represents if the field is read-only or not.
userThe currently authenticated user. More details.
validateA function that can be used to validate the field.

Sending and receiving values from the form

When swapping out the Field component, you are responsible for sending and receiving the field's value from the form itself.

To do so, import the useField hook from @payloadcms/ui and use it to manage the field's value:

1
'use client'
2
import { useField } from '@payloadcms/ui'
3
4
export const CustomTextField: React.FC = () => {
5
const { value, setValue } = useField()
6
7
return (
8
<input
9
onChange={(e) => setValue(e.target.value)}
10
value={value}
11
/>
12
)
13
}

TypeScript

When building Custom Field Components, you can import the component type to ensure type safety. There is an explicit type for the Field Component, one for every Field Type and for every client/server environment. The convention is to prepend the field type onto the target type, i.e. TextFieldClientComponent:

1
import type {
2
TextFieldClientComponent,
3
TextFieldServerComponent,
4
TextFieldClientProps,
5
TextFieldServerProps,
6
// ...and so on for each Field Type
7
} from 'payload'

The field Prop

All Field Components are passed their own Field Config through a common field prop. Within a Server Component, this is the raw Field Config. Within Client Components, however, the raw Field Config is non-serializable. Instead, Client Components receives a Client Config, which is a sanitizes version of the Field Config that is safe to pass into Client Components.

The exact shape of this prop is unique to the specific Field Type being rendered, minus all non-serializable properties. Any Custom Components are also resolved into a "mapped component" that is safe to pass.

1
import React from 'react'
2
import type { TextFieldServerComponent } from 'payload'
3
4
export const MyServerTextField: TextFieldServerComponent = ({ payload, field: { name } }) => {
5
const result = await payload.find({
6
collection: 'myCollection',
7
depth: 1,
8
})
9
10
// ...
11
}

Client Component:

1
'use client'
2
import React from 'react'
3
import type { TextFieldClientComponent } from 'payload'
4
5
export const MyClientTextField: TextFieldClientComponent = ({ field: { name } }) => {
6
return (
7
<p>
8
{`This field's name is ${name}`}
9
</p>
10
)
11
}

The following additional properties are also provided to the field prop:

PropertyDescription
_isPresentationalA boolean indicating that the field is purely visual and does not directly affect data or change data shape, i.e. the UI Field.
_pathA string representing the direct, dynamic path to the field at runtime, i.e. myGroup.myArray[0].myField.
_schemaPathA string representing the direct, static path to the Field Config, i.e. myGroup.myArray.myField

TypeScript

When building Custom Field Components, you can import the client field props to ensure type safety in your component. There is an explicit type for the Field Component, one for every Field Type and server/client environment. The convention is to prepend the field type onto the target type, i.e. TextFieldClientComponent:

1
import type {
2
TextFieldClientComponent,
3
TextFieldServerComponent,
4
TextFieldClientProps,
5
TextFieldServerProps,
6
// ...and so on for each Field Type
7
} from 'payload'

The Cell Component

The Cell Component is rendered in the table of the List View. It represents the value of the field when displayed in a table cell.

To easily swap in your own Cell Component, use the admin.components.Cell property in your Field Config:

1
import type { Field } from 'payload'
2
3
export const myField: Field = {
4
name: 'myField',
5
type: 'text',
6
admin: {
7
components: {
8
Cell: '/path/to/MyCustomCellComponent',
9
},
10
},
11
}

For details on how to build Custom Components, see Building Custom Components.

All Cell Components receive the following props:

PropertyDescription
fieldThe sanitized, client-friendly version of the field's config. More details
linkA boolean representing whether this cell should be wrapped in a link.
onClickA function that is called when the cell is clicked.

The Label Component

The Label Component is rendered anywhere a field needs to be represented by a label. This is typically used in the Edit View, but can also be used in the List View and elsewhere.

To easily swap in your own Label Component, use the admin.components.Label property in your Field Config:

1
import type { Field } from 'payload'
2
3
export const myField: Field = {
4
name: 'myField',
5
type: 'text',
6
admin: {
7
components: {
8
Label: '/path/to/MyCustomLabelComponent',
9
},
10
},
11
}

For details on how to build Custom Components, see Building Custom Components.

Custom Label Components receive all Field Component props, plus the following props:

PropertyDescription
fieldThe sanitized, client-friendly version of the field's config. More details

TypeScript

When building Custom Label Components, you can import the component props to ensure type safety in your component. There is an explicit type for the Label Component, one for every Field Type and server/client environment. The convention is to append LabelServerComponent or LabelClientComponent to the type of field, i.e. TextFieldLabelClientComponent.

1
import type {
2
TextFieldLabelServerComponent,
3
TextFieldLabelClientComponent,
4
// ...and so on for each Field Type
5
} from 'payload'

The Error Component

The Error Component is rendered when a field fails validation. It is typically displayed beneath the field input in a visually-compelling style.

To easily swap in your own Error Component, use the admin.components.Error property in your Field Config:

1
import type { Field } from 'payload'
2
3
export const myField: Field = {
4
name: 'myField',
5
type: 'text',
6
admin: {
7
components: {
8
Error: '/path/to/MyCustomErrorComponent',
9
},
10
},
11
}

For details on how to build Custom Components, see Building Custom Components.

Custom Error Components receive all Field Component props, plus the following props:

PropertyDescription
fieldThe sanitized, client-friendly version of the field's config. More details

TypeScript

When building Custom Error Components, you can import the component props to ensure type safety in your component. There is an explicit type for the Error Component, one for every Field Type and server/client environment. The convention is to append ErrorServerComponent or ErrorClientComponent to the type of field, i.e. TextFieldErrorClientComponent.

1
import type {
2
TextFieldErrorServerComponent,
3
TextFieldErrorClientComponent,
4
// And so on for each Field Type
5
} from 'payload'

The Description Property

Field Descriptions are used to provide additional information to the editor about a field, such as special instructions. Their placement varies from field to field, but typically are displayed with subtle style differences beneath the field inputs.

A description can be configured in three ways:

To easily add a Custom Description to a field, use the admin.description property in your Field Config:

1
import type { SanitizedCollectionConfig } from 'payload'
2
3
export const MyCollectionConfig: SanitizedCollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
name: 'myField',
9
type: 'text',
10
admin: {
11
description: 'Hello, world!'
12
},
13
},
14
]
15
}

Description Functions

Custom Descriptions can also be defined as a function. Description Functions are executed on the server and can be used to format simple descriptions based on the user's current Locale.

To easily add a Description Function to a field, set the admin.description property to a function in your Field Config:

1
import type { SanitizedCollectionConfig } from 'payload'
2
3
export const MyCollectionConfig: SanitizedCollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
name: 'myField',
9
type: 'text',
10
admin: {
11
description: ({ t }) => `${t('Hello, world!')}`
12
},
13
},
14
]
15
}

All Description Functions receive the following arguments:

ArgumentDescription
tThe t function used to internationalize the Admin Panel. More details

The Description Component

Alternatively to the Description Property, you can also use a Custom Component as the Field Description. This can be useful when you need to provide more complex feedback to the user, such as rendering dynamic field values or other interactive elements.

To easily add a Description Component to a field, use the admin.components.Description property in your Field Config:

1
import type { SanitizedCollectionConfig } from 'payload'
2
3
export const MyCollectionConfig: SanitizedCollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
name: 'myField',
9
type: 'text',
10
admin: {
11
components: {
12
Description: '/path/to/MyCustomDescriptionComponent',
13
}
14
}
15
}
16
]
17
}

For details on how to build a Custom Description, see Building Custom Components.

Custom Description Components receive all Field Component props, plus the following props:

PropertyDescription
fieldThe sanitized, client-friendly version of the field's config. More details

TypeScript

When building Custom Description Components, you can import the component props to ensure type safety in your component. There is an explicit type for the Description Component, one for every Field Type and server/client environment. The convention is to append DescriptionServerComponent or DescriptionClientComponent to the type of field, i.e. TextFieldDescriptionClientComponent.

1
import type {
2
TextFieldDescriptionServerComponent,
3
TextFieldDescriptionClientComponent,
4
// And so on for each Field Type
5
} from 'payload'

afterInput and beforeInput

With these properties you can add multiple components before and after the input element, as their name suggests. This is useful when you need to render additional elements alongside the field without replacing the entire field component.

To add components before and after the input element, use the admin.components.beforeInput and admin.components.afterInput properties in your Field Config:

1
import type { SanitizedCollectionConfig } from 'payload'
2
3
export const MyCollectionConfig: SanitizedCollectionConfig = {
4
// ...
5
fields: [
6
// ...
7
{
8
name: 'myField',
9
type: 'text',
10
admin: {
11
components: {
12
beforeInput: ['/path/to/MyCustomComponent'],
13
afterInput: ['/path/to/MyOtherCustomComponent'],
14
}
15
}
16
}
17
]
18
}

For details on how to build Custom Components, see Building Custom Components.

Conditional Logic

You can show and hide fields based on what other fields are doing by utilizing conditional logic on a field by field basis. The condition property on a field's admin config accepts a function which takes three arguments:

  • data - the entire document's data that is currently being edited
  • siblingData - only the fields that are direct siblings to the field with the condition
  • { user } - the final argument is an object containing the currently authenticated user

The condition function should return a boolean that will control if the field should be displayed or not.

Example:

1
{
2
fields: [
3
{
4
name: 'enableGreeting',
5
type: 'checkbox',
6
defaultValue: false,
7
},
8
{
9
name: 'greeting',
10
type: 'text',
11
admin: {
12
condition: (data, siblingData, { user }) => {
13
if (data.enableGreeting) {
14
return true
15
} else {
16
return false
17
}
18
},
19
},
20
},
21
]
22
}
