Custom Fields for Filament v5

Let your end-users add dynamic fields to any Eloquent model + Filament resource at runtime, without writing a single migration. Ships an admin CRUD for managing field definitions, an Eloquent trait that auto-merges the new columns into your model's fillable/casts, a Filament resource trait with five merge helpers that inject fields into forms, tables, filters, infolists, and a runtime schema manager that creates the underlying DB columns for you.

Features

Eloquent trait (HasCustomFields) — drop onto any model; custom field codes auto-merge into $fillable and $casts at runtime
Filament resource trait — 5 one-line merge helpers: mergeCustomFormFields, mergeCustomTableColumns, mergeCustomTableFilters, mergeCustomTableQueryBuilderConstraints, mergeCustomInfolistEntries
Admin CRUD (/admin/custom-fields) — create, edit, sort, soft-delete dynamic fields per resource, with full validation / formatting settings
11 field types via FieldType enum — Text, Textarea, Select, Checkbox, Radio, Toggle, CheckboxList, DateTime, Editor, Markdown, ColorPicker
8 text input types via InputType enum — Text, Email, Numeric, Integer, Password, Tel, Url, Color
Schema manager (CustomFieldsColumnManager) — programmatically add / drop DB columns when fields are created or deleted
Table integration — the defined fields automatically surface as CustomColumns (if use_in_table=true) and CustomFilters
Spatie-sortable — drag-to-reorder fields with order_column_name=sort
Soft deletes — recover deleted field definitions
Policy + permissions — Filament Shield compatible, with view_any_field_field, create_field_field etc.
Translations — en and ar shipped (navigation + form labels + validation names + setting names)
Pest test suite — architecture + model + policy + trait + components + enums (31 tests)

Requirements

PHP 8.2+
Laravel 11+
Filament v5+
spatie/eloquent-sortable v4 (already a Filament dependency)

Installation

composer require aureuserp/custom-fields

The service provider is auto-discovered. The migration is registered via Spatie's package-tools and run on php artisan migrate.

php artisan migrate

Note

Migrating from webkul/fields: the custom_fields table migration keeps its original timestamp filename, so existing installations will see it already applied — no duplicate-table errors, no re-run.

Quick start

1. Mark your model

use Illuminate\Database\Eloquent\Model;
use Webkul\CustomFields\Concerns\HasCustomFields;

class Employee extends Model
{
    use HasCustomFields;
}

Any custom field code defined against Webkul\Employee\Models\Employee is now mass-assignable and properly cast.

2. Extend your Filament resource

use Filament\Resources\Resource;
use Filament\Schemas\Schema;
use Webkul\CustomFields\Filament\Concerns\HasCustomFields;

class EmployeeResource extends Resource
{
    use HasCustomFields;

    public static function form(Schema $schema): Schema
    {
        return $schema->components(
            static::mergeCustomFormFields([
                // your base fields
            ])
        );
    }

    public static function table(Table $table): Table
    {
        return $table
            ->columns(static::mergeCustomTableColumns([ /* base */ ]))
            ->filters(static::mergeCustomTableFilters([ /* base */ ]));
    }
}

3. Define fields in the admin CRUD

Visit /admin/custom-fields → New field → pick a resource → pick a field type → configure options/validations → save.

The field now appears in the resource's form, table, filters, and infolist automatically.

API reference

Eloquent trait

Webkul\CustomFields\Concerns\HasCustomFields

Boots three lifecycle listeners (retrieved, creating, updating) that call loadCustomFields():

loadCustomFields() — queries Field::where('customizable_type', get_class($this)), merges every field's code into $fillable and applies type-appropriate casts.
mergeFillable(array $attributes) — public helper exposed for ad-hoc merging.
mergeCasts($attributes) — public helper; accepts either an array (passes through to parent) or a Collection of Field records.
getCustomFields() (protected) — override this if you want to scope the query (e.g. to a specific tenant).

Type-to-cast mapping:

Field type	Cast
`select` (multiselect)	`array`
`select` (single)	`string`
`checkbox`, `toggle`	`boolean`
`checkbox_list`	`array`
everything else	`string`

Filament resource trait

Webkul\CustomFields\Filament\Concerns\HasCustomFields

Five static helpers — each accepts a base array + optional include/exclude lists and returns base + custom:

static::mergeCustomFormFields(array $base, array $include = [], array $exclude = []): array
static::mergeCustomTableColumns(array $base, array $include = [], array $exclude = []): array
static::mergeCustomTableFilters(array $base, array $include = [], array $exclude = []): array
static::mergeCustomTableQueryBuilderConstraints(array $base, array $include = [], array $exclude = []): array
static::mergeCustomInfolistEntries(array $base, array $include = [], array $exclude = []): array

include=[] means "all fields"; a non-empty list whitelists field codes. exclude blacklists field codes.

Components

Each injector is also usable standalone:

use Webkul\CustomFields\Filament\Forms\Components\CustomFields;
use Webkul\CustomFields\Filament\Infolists\Components\CustomEntries;
use Webkul\CustomFields\Filament\Tables\Columns\CustomColumns;
use Webkul\CustomFields\Filament\Tables\Filters\CustomFilters;

CustomFields::make(MyResource::class)
    ->include(['hobbies'])
    ->exclude(['internal_notes'])
    ->getSchema();

Column manager

Webkul\CustomFields\CustomFieldsColumnManager

Three static methods called on Field model lifecycle (create/update/delete):

createColumn(Field $field) — adds the column to the customisable model's table with the appropriate DB type
updateColumn(Field $field) — creates the column if missing (for rename/resurrect scenarios)
deleteColumn(Field $field) — drops the column

The DB type mapping uses getColumnType() which routes via FieldType::tryFrom($field->type):

Field type	DB column type
`text`	`string` / `integer` / `decimal` (based on `input_type`)
`textarea`, `editor`, `markdown`	`text`
`select` (multiselect)	`json`
`select` (single), `radio`, `color`	`string`
`checkbox`, `toggle`	`boolean`
`checkbox_list`	`json`
`datetime`	`datetime`

Enums

Enum	Cases → values	Default
`FieldType`	`Text='text'`, `Textarea='textarea'`, `Select='select'`, `Checkbox='checkbox'`, `Radio='radio'`, `Toggle='toggle'`, `CheckboxList='checkbox_list'`, `DateTime='datetime'`, `Editor='editor'`, `Markdown='markdown'`, `ColorPicker='color'`	`FieldType::Text`
`InputType`	`Text`, `Email`, `Numeric`, `Integer`, `Password`, `Tel`, `Url`, `Color`	`InputType::Text`

Both enums expose a default() static for symbolic-constant fallbacks:

use Webkul\CustomFields\Enums\FieldType;
use Webkul\CustomFields\Enums\InputType;

$type = FieldType::tryFrom($raw) ?? FieldType::default();

Real-world example

Here's a full Employee resource adopting the trait. End-users can add a "hobbies" multiselect via the admin CRUD; the field flows through form, table, and infolist automatically.

use Filament\Forms\Components\Select;
use Filament\Forms\Components\TextInput;
use Filament\Resources\Resource;
use Filament\Schemas\Schema;
use Filament\Tables\Columns\TextColumn;
use Filament\Tables\Table;
use Webkul\CustomFields\Filament\Concerns\HasCustomFields;
use Webkul\Employee\Models\Employee;

class EmployeeResource extends Resource
{
    use HasCustomFields;

    protected static ?string $model = Employee::class;

    public static function form(Schema $schema): Schema
    {
        return $schema->components(static::mergeCustomFormFields([
            TextInput::make('name')->required(),
            Select::make('department_id')->relationship('department', 'name'),
        ]));
    }

    public static function table(Table $table): Table
    {
        return $table
            ->columns(static::mergeCustomTableColumns([
                TextColumn::make('name'),
            ]))
            ->filters(static::mergeCustomTableFilters([]));
    }
}

And the Eloquent side:

use Webkul\CustomFields\Concerns\HasCustomFields;

class Employee extends Model
{
    use HasCustomFields;

    protected $fillable = ['name', 'department_id'];
}

// After an admin defines a "hobbies" checkbox_list field:
$employee = Employee::create([
    'name' => 'Alice',
    'department_id' => 1,
    'hobbies' => ['chess', 'hiking'],  // ← custom field, automatically fillable + cast to array
]);

$employee->hobbies;  // ['chess', 'hiking']  ← automatically cast from JSON

Translations

Ships with en and ar under the custom-fields:: namespace. Publish to customise:

php artisan vendor:publish --tag="custom-fields-translations"

The translation file includes 70+ validation rule labels, 200+ Filament setting names, plus navigation and form labels for the admin CRUD.

Configuration

Every navigation / identity / placement setting is configurable two ways — pick whichever fits your project:

1. Fluent setters in your panel provider (recommended for per-panel overrides)

// app/Providers/Filament/AdminPanelProvider.php
use Webkul\CustomFields\CustomFieldsPlugin;

->plugins([
    CustomFieldsPlugin::make()
        ->navigationGroup(__('admin.navigation.setting'))
        ->navigationLabel('Custom Fields')
        ->navigationIcon('heroicon-o-puzzle-piece')
        ->navigationSort(50)
        ->navigationBadge(fn () => \Webkul\CustomFields\Models\Field::count())
        ->navigationBadgeColor('primary')
        ->slug('admin/custom-fields')
        ->cluster(\App\Filament\Clusters\AdminTools::class),
])

2. Publishable config file (recommended for app-wide defaults)

php artisan vendor:publish --tag="custom-fields-config"

That writes config/custom-fields.php to your app. Edit any key:

// config/custom-fields.php
return [
    'navigation' => [
        'label'   => 'Custom Fields',
        'group'   => 'Settings',
        'icon'    => 'heroicon-o-puzzle-piece',
        'sort'    => 50,
        'badge'   => null,
        'register'=> true,
    ],
    'resource' => [
        'register'           => true,
        'slug'               => 'admin/custom-fields',
        'cluster'            => \App\Filament\Clusters\AdminTools::class,
        'model_label'        => null,
        'plural_model_label' => null,
    ],
];

Resolution order

When the Resource renders, each value is resolved by the first matching rule:

Fluent setter on CustomFieldsPlugin::make()->…() — highest priority
Config file config('custom-fields.*') — if the setter was not called
Hardcoded fallback in getPluginDefaults() — when both above are null

Full setter → config key map

Fluent setter	Config key
`navigationLabel($v)`	`custom-fields.navigation.label`
`navigationGroup($v)`	`custom-fields.navigation.group`
`navigationIcon($v)`	`custom-fields.navigation.icon`
`activeNavigationIcon($v)`	`custom-fields.navigation.active_icon`
`navigationSort($v)`	`custom-fields.navigation.sort`
`navigationBadge($v)`	`custom-fields.navigation.badge`
`navigationBadgeColor($v)`	`custom-fields.navigation.badge_color`
`navigationBadgeTooltip($v)`	`custom-fields.navigation.badge_tooltip`
`navigationParentItem($v)`	`custom-fields.navigation.parent_item`
`subNavigationPosition($v)`	`custom-fields.navigation.sub_position`
`registerNavigation($bool)`	`custom-fields.navigation.register`
`modelLabel($v)`	`custom-fields.resource.model_label`
`pluralModelLabel($v)`	`custom-fields.resource.plural_model_label`
`slug($v)`	`custom-fields.resource.slug`
`cluster($class)`	`custom-fields.resource.cluster`
`tenantRelationshipName($v)`	`custom-fields.resource.tenant_relationship`
`registerResource($bool)`	`custom-fields.resource.register`

Disable the admin CRUD entirely

Only want the Eloquent trait + table-injection API, not the admin menu?

CustomFieldsPlugin::make()->registerResource(false),
// or in config/custom-fields.php:
'resource' => ['register' => false],

The FieldResource routes are skipped; everything else still works.

Publishing resources

Testing

vendor/bin/pest plugins/aureuserp/custom-fields/tests/Feature

31 tests (114 assertions) across:

Area	Coverage
Architecture	Field model extends Eloquent Model + implements Sortable, Plugin implements `Filament\Contracts\Plugin`, SP extends Spatie, no debug calls in shipped code
Enums	`FieldType` / `InputType` — all cases have expected values, `default()` works, `tryFrom` returns null for unknown
Field model	Table name, fillable, casts, SoftDeletes trait, Sortable config
Policy	All 10 CRUD + soft-delete permission methods exist
Eloquent trait	Trait exists, applies to host model without error, `mergeFillable` dedups, declares `fill` / `mergeCasts`
Filament trait	Trait exists, all 5 merge helpers declared, merge helpers combine base + custom arrays
Component API	`CustomFields/Entries/Columns/Filters::make()->include()->exclude()` chainable and return `static`
Column manager	Exposes `createColumn`/`updateColumn`/`deleteColumn` static methods

Troubleshooting

Symptom	Fix
`Class not found` for `Webkul\CustomFields\…`	`composer dump-autoload && php artisan optimize:clear`
Trait methods not firing	Confirm the Eloquent trait is on your model (`use HasCustomFields;`) and that `Field::where('customizable_type', …)` returns rows
Custom column doesn't appear in the DB	Check `CustomFieldsColumnManager::createColumn()` ran — it's called from `CreateField::afterCreate()` on save. Verify the host table already exists.
Policy denies everything	Generate Shield policies: `php artisan shield:generate --resource=FieldResource`
`custom_fields` table missing	Run `php artisan migrate`
