Supports Filament v4 and v5. If you are currently using Filament v3, please refer to this link here

Filament nestedset tree build on kalnoy/nestedset, support multi language. support Multi-tenancy

#Overview

• Elegant UI, consistent with the default style of the filament page
• The Filament nestedset plugin is built on kalnoy/nestedset
• ParentSelect field depends on codewithdennis/filament-select-tree
• Some features are borrowed from 15web/filament-tree
• Support multi-tenancy, you can easily create nestedset pages among multiple tenants
• Nestedset level is unlimited by default, but you can limit the nestedset levels if you wish
• Support tabs consistent with the Listing records of the filament panel. You can switch between different nestedset data through tabs on the current page

#Screenshots

#Installation

You can install the package via composer:

composer require wsmallnews/filament-nestedset:^2.0

The current release is compatible with both Filament v4 and v5.

You can publish the config file with:

php artisan vendor:publish --tag="sn-filament-nestedset-config"

Optionally, you can publish the views using

php artisan vendor:publish --tag="sn-filament-nestedset-views"

Multi language support, you can publish the language files using

php artisan vendor:publish --tag="sn-filament-nestedset-translations"

This is the contents of the published config file:

return [
    /**
     * Restrict deletion of nodes with children
     */
    'allow_delete_parent' => false,

    /*
     * Restrict deletion of root nodes, even if 'allow_delete_parent' is true, root nodes can be deleted.
     */
    'allow_delete_root' => false,

    /**
     * create action show parent select field
     */
    'create_action_modal_show_parent_select' => true,

    /**
     * Display the "Create Child Node" action in each row (if 'create_action_modal_show_parent_select' is false, This field should be set to true)
     */
    'show_create_child_node_action_in_row' => true,

    /**
     * By default, the CSS file will be automatically loaded globally. If you use a filament custom theme, you can disable the automatic loading of the CSS file
     */
    'autoload_assets' => true,
];

#Prepare your model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Kalnoy\Nestedset\NodeTrait;
...

class YouModel extends Model
{
    use NodeTrait;

    ...
}

You should add fields to your model. replacing your_model_table with the name of your model table

Add fields in the new model

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up(): void
    {
        Schema::create('your_model_table', function (Blueprint $table) {
            ...
            $table->nestedSet();
            ...
        });
    }
};

Add fields to an existing model

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up(): void
    {
        Schema::table('your_model_table', function (Blueprint $table) {
            $table->nestedSet();
        });
    }
};

And run the migration

php artisan migrate

#Usage

#Create the nestedset page

php artisan make:filament-nestedset-page

#Please define attribute name of the nodes in your tree, eg. title or name

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected static string $recordTitleAttribute = 'name';
    ...

}

By default, the plugin will use the recordTitleAttribute attribute to display the node name in the tree. If you want to use another attribute, you can define the getRecordLabel method, Support HtmlString.

<?php

namespace App\Filament\Pages;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\HtmlString;
use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    public function getRecordLabel(Model $item): HtmlString | string
    {
        return $item->{static::getRecordTitleAttribute()} ?? ' ';
    }
    ...
}

#Define form schema

If the schema for create and edit are the same, you can define the schema method.

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected function schema(array $arguments): array
    {
        return [
            //
        ];
    }
    ...
}

If the schema for create and edit are different, you can define createSchema and editSchema methods separately.

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected function createSchema(array $arguments): array
    {
        return [
            //
        ];
    }
    protected function editSchema(array $arguments): array
    {
        return [
            //
        ];
    }

    ...
}

#Define the prompt text when the tree is empty

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected static ?string $emptyLabel = 'no test data';

    ...

}

#Limit nestedset level

Nestedset level is unlimited by default, you can limit the nestedset levels by:

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected static ?int $level = 3;

    // Alternatively, you may use the getLevel() to define a dynamic level

    public function getLevel(): ?int
    {
        return static::$level;
    }

    ...

}

#Other customizable properties

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected static ?string $model = NavigationModel::class;
    
    protected static ?string $modelLabel = 'Test Management';

    protected static ?string $title = 'Page Title';

    protected static ?string $navigationLabel = 'Test Navigation';

    protected static ?string $navigationGroup = 'Test Group';

    protected static ?string $slug = 'tests';

    protected static string $recordTitleAttribute = 'name';

    protected static ?string $pluralModelLabel = 'Test Management';

    protected static ?int $navigationSort = 1;

    ...
}

#Display additional attributes

You can define additional attributes to display in each row through the infolistSchema method

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...
    protected function infolistSchema(): array
    {
        return [];
    }
    ...
}

By default, the infolist will be displayed at the md breakpoint and above. You can change the display breakpoint by setting $infolistHiddenEndpoint.

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...
    protected static string $infolistHiddenEndpoint = 'lg';
    ...
}

By default, the infolist will be right-aligned. You can change the alignment by setting $infolistAlignment.

<?php

namespace App\Filament\Pages;

use Filament\Support\Enums\Alignment;
use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...
    protected static Alignment $infolistAlignment = Alignment::Left;
    ...
}

#Advanced features

#Multi-tenancy support

Multi-tenancy features is supported by default. If your filament panel supports multi-tenancy, you need to add the getScopeAttributes method to your model and add the team_id field.

Multi-tenancy features is implemented based on kalnoy/nestedset scoped feature. You can view detailed documentation here

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
...

class YouModel extends Model
{
    ...

    public function getScopeAttributes(): array
    {
        return ['team_id', ...];
    }

    ...
}

If your filament panel supports multi-tenancy, but the current page doesn't need to distinguish tenancy, just set $isScopedToTenant = false in the page.

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...
    protected static bool $isScopedToTenant = false;
    ...
}

#Tabs support

Tabs are implemented based on kalnoy/nestedset scoped feature. You can view detailed documentation here

Set the associated tab field name using tabFieldName. And setting tabs array, you don't need to add the current tab condition on the tab, as the tab condition will be automatically appended to kalnoy/nestedset scoping parameters.

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    protected static ?string $tabFieldName = 'type';

    public function getTabs(): array
    {
        return [
            'web' => Tab::make()->label('Website Navigation'),
            'shop' => Tab::make()->label('Shop Navigation')
        ];
    }

    ...
}

You need to add the getScopeAttributes method to your model and add the field set by tabFieldName (type in this case).

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
...

class YouModel extends Model
{
    ...

    public function getScopeAttributes(): array
    {
        return ['type', ...];
    }

    ...
}

#Additional scope parameters

If you need to set additional scope parameters for kalnoy/nestedset scoping

Define the nestedScoped method

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    public function nestedScoped()
    {
        return ['category_id' => 5];
    }
    ...
}

You need to add the getScopeAttributes method to your model and add the field set.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
...

class YouModel extends Model
{
    ...

    public function getScopeAttributes(): array
    {
        return ['category_id', ...];
    }

    ...
}

#Add custom eloquent query conditions

<?php

namespace App\Filament\Pages;

use Wsmallnews\FilamentNestedset\Pages\NestedsetPage;

class Test extends NestedsetPage
{
    ...

    public function getEloquentQuery($query)
    {
        return $query->where('status', 'normal');
    }
    ...
}

#Nestedset Livewire component

#Overview

• The property showLevel can be set to nestedset show level
• The property emptyLabel can be set to nestedset empty state
• The method getRecordLabel custom nestedset node label
• The method getHasActive mark active status
• You can customize the view by using the view and recordView properties
• You can use the getRecordUrl method to customize the href jump link, which defaults to inserting href="JavaScript:;"
• When clicking on the nestedset leaf node, a sn-filament-nestedset-leaf-click event will be triggered
• When clicking on nestedset non leaf nodes, a sn-filament-nestedset-node-click event will be triggered
• Suggest choosing between event and getRecordUrl

#Example

<?php

namespace App\Livewire\Components;

use App\Models\Category;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\HtmlString;
use Livewire\Attributes\On;
use Wsmallnews\FilamentNestedset\Livewire\Components\Nestedset;

use function Filament\Support\generate_href_html;

class Categories extends Nestedset
{
    public function getRecordLabel(Model $record): HtmlString | string
    {
        return $record->name_label;
    }

    public function getHasActive(Model $record): bool
    {
        return $record->has_active;
    }

    #[On('sn-filament-nestedset-leaf-click')]
    public function clickCategory($recordId)
    {
        $this->categoryId = $recordId;
    }
    // ... or
    public function getRecordUrl(Model $record): string | HtmlString | null
    {
        return generate_href_html(route('categories.show', $record->id), false);
    }


    public function getNestedset()
    {
        return Category::normal()->defaultOrder()
            ->get()->toTree();
    }
}

#Custom theme

By default, the CSS file will be automatically loaded globally. If you use a filament custom theme, you can disable the automatic loading of the CSS file

Disable the automatic loading of the CSS file

<?php
return [
    ...
    
    'autoload_assets' => false,
];

You should add the following code to your custom theme file. If you custom theme file is /resources/css/filament/admin/theme.css

@import '../../../../vendor/wsmallnews/filament-nestedset/resources/css/index.css';
