Installation

To install the package, run the following command:

composer require solution-forest/filament-tree

Important: Need to publish assets after version 2.x

php artisan filament:assets

Note: Add plugin Blade files to your custom theme tailwind.config.js for dark mode.

To set up your own custom theme, you can visit the official instruction page on the Filament website.

Add the plugin's views to your tailwind.config.js file.

content: [
    '<path-to-vendor>/solution-forest/filament-tree/resources/**/*.blade.php',
]

Then, publish the config file using:

php artisan vendor:publish --tag="filament-tree-config"

You can set your preferred options by adding the following code to your config/filament-tree.php file:

<?php

return [
    /**
     * Tree model fields
     */
    'column_name' => [
        'order' => 'order',
        'parent' => 'parent_id',
        'title' => 'title',
    ],
    /**
     * Tree model default parent key
     */
    'default_parent_id' => -1,
    /**
     * Tree model default children key name
     */
    'default_children_key_name' => 'children',
];

Usage

Prepare the database and model

To use Filament Tree, follow these table structure conventions:

Tip: The parent_id field must always default to -1!!!

Schema::create('product_categories', function (Blueprint $table) {
    $table->id();
    $table->integer('parent_id')->default(-1);
    $table->integer('order')->default(0)->index();
    $table->string('title');
    $table->timestamps();
});

This plugin provides a convenient method called treeColumns() that you can use to add the required columns for the tree structure to your table more easily. Here's an example:

Schema::create('product_categories', function (Blueprint $table) {
    $table->id();
    $table->treeColumns();
    $table->timestamps();
});

This will automatically add the required columns for the tree structure to your table.

The above table structure contains three required fields: parent_id, order, title, and other fields do not have any requirements.

The corresponding model is app/Models/ProductCategory.php:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use SolutionForest\FilamentTree\Concern\ModelTree;

class ProductCategory extends Model
{
    use ModelTree;

    protected $fillable = ["parent_id", "title", "order"];

    protected $table = 'product_categories';
}

The field names of the three fields parent_id, order, and title in the table structure can also be modified:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use SolutionForest\FilamentTree\Concern\ModelTree;

class ProductCategory extends Model
{
    use ModelTree;

    protected $fillable = ["parent_id", "title", "order"];

    protected $table = 'product_categories';

    // Default if you need to override

    // public function determineOrderColumnName(): string
    // {
    //     return "order";
    // }

    // public function determineParentColumnName(): string
    // {
    //     return "parent_id";
    // }

    // public function determineTitleColumnName(): string
    // {
    //     return 'title';
    // }

    // public static function defaultParentKey()
    // {
    //     return -1;
    // }

    // public static function defaultChildrenKeyName(): string
    // {
    //     return "children";
    // }

}

Widget

Filament provides a powerful feature that allows you to display widgets inside pages, below the header and above the footer. This can be useful for adding additional functionality to your resource pages.

To create a Tree Widget and apply it to a resource page, you can follow these steps:

1. Creating a Filament Resource Page

To create a resources page, run the following command:

php artisan make:filament-resource ProductCategory

2. Create Tree Widget

Prepare the filament-tree Widget and show it in Resource page.

php artisan make:filament-tree-widget ProductCategoryWidget

Now you can see the Widget in Filament Folder

<?php

namespace App\Filament\Widgets;

use App\Models\ProductCategory as ModelsProductCategory;
use App\Filament\Widgets;
use Filament\Forms\Components\TextInput;
use SolutionForest\FilamentTree\Widgets\Tree as BaseWidget;

class ProductCategoryWidget extends BaseWidget
{
    protected static string $model = ModelsProductCategory::class;

    // you can customize the maximum depth of your tree
    protected static int $maxDepth = 2;

    protected ?string $treeTitle = 'ProductCategory';

    protected bool $enableTreeTitle = true;

    protected function getFormSchema(): array
    {
        return [
            TextInput::make('title'),
        ];
    }
}

3. Displaying a widget on a resource page

Once you have created the widget, modify the getHeaderWidgets() or getFooterWidgets() methods of the resource page to show the tree view:

<?php

namespace App\Filament\Resources\ProductCategoryResource\Pages;

use App\Filament\Resources\ProductCategoryResource;
use App\Filament\Widgets\ProductCategory;
use Filament\Pages\Actions;
use Filament\Resources\Pages\ListRecords;

class ListProductCategories extends ListRecords
{
    protected static string $resource = ProductCategoryResource::class;

    protected function getActions(): array
    {
        return [
            Actions\CreateAction::make(),
        ];
    }

    protected function getHeaderWidgets(): array
    {
        return [
            ProductCategory::class
        ];
    }
}

Resources

Filament allows you to create a custom pages for resources, you also can create a tree page that display hierarchical data.

Create a Page

To create a tree page for resource, you can use:

php artisan make:filament-tree-page ProductCategoryTree --resource=ProductCategory

Register a Page to the resource

You must register the tree page to a route in the static getPages() methods of your resource. For example:

public static function getPages(): array
{
    return [
        // ...
        'tree-list' => Pages\ProductCategoryTree::route('/tree-list'),
    ];
}

Actions

Define the available "actions" for the tree page using the getActions() and getTreeActions() methods of your page class.

The getActions() method defines actions that are displayed next to the page's heading:

    use Filament\Pages\Actions\CreateAction;

    protected function getActions(): array
    {
        return [
            CreateAction::make(),
            // SAMPLE CODE, CAN DELETE
            //\Filament\Pages\Actions\Action::make('sampleAction'),
        ];
    }

The getTreeActions() method defines the actions that are displayed for each record in the tree. For example:

use Filament\Pages\Actions\Action;

protected function getTreeActions(): array
{
    return [
        Actions\ViewAction::make(),
        Actions\EditAction::make(),
        Actions\DeleteAction::make(),
    ];
}

Alternatively, you can use the hasDeleteAction(), hasEditAction(), and hasViewAction() methods to customize each action individually.

protected function hasDeleteAction(): bool
{
    return false;
}

protected function hasEditAction(): bool
{
    return true;
}

protected function hasViewAction(): bool
{
    return false;
}

Record ICON

To customize the prefix icon for each record in a tree page, you can use the getTreeRecordIcon() method in your tree page class. This method should return a string that represents the name of the icon you want to use for the record. For example:

public function getTreeRecordIcon(?\Illuminate\Database\Eloquent\Model $record = null): ?string
{
    // default null
    return 'heroicon-o-cake';
}

Node collapsed state

You can customize a collapsed state of the node. If you would like to show your tree initially collapsed you can use:

public function getNodeCollapsedState(?\Illuminate\Database\Eloquent\Model $record = null): bool
{
    // All tree nodes will be collapsed by default.
    return true;
}

Record Title

To customize the ttile for each record in a tree page, you can use the getTreeRecordTitle() method in your tree page class. This method should return a string that represents the name of the icon you want to use for the record. For example:

public function getTreeRecordTitle(?\Illuminate\Database\Eloquent\Model $record = null): string
{
    if (! $record) {
        return '';
    }
    $id = $record->getKey();
    $title = $record->{(method_exists($record, 'determineTitleColumnName') ? $record->determineTitleColumnName() : 'title')};
    return "[{$id}] {$title}";
}

Pages

This plugin enables you to create tree pages in the admin panel. To create a tree page for a model, use the make:filament-tree-page command. For example, to create a tree page for the ProductCategory model, you can run:

Create a Page

Tip: Note that you should make sure the model contains the required columns or already uses the ModelTree trait

php artisan make:filament-tree-page ProductCategory --model=ProductCategory

Actions, Widgets and Icon for each record

Once you've created the tree page, you can customize the available actions, widgets, and icon for each record. You can use the same methods as for resource pages. See the Resource Page for more information on how to customize actions, widgets, and icons.

Translation

Suggest used with Spatie Translatable (https://filamentphp.com/plugins/filament-spatie-translatable) Plugin.

1. Ensure your model already apply translatable setup. (Refence on https://spatie.be/docs/laravel-translatable/v6/installation-setup)

use Filament\Actions\LocaleSwitcher;
use SolutionForest\FilamentTree\Concern\ModelTree;
use Spatie\Translatable\HasTranslations;

class Category extends Model
{
    use HasTranslations;
    use TreeModel;

    protected $translatable = [
        'title',
    ];
}

1. You need to add the necessary trait and LocaleSwitcher header action to your tree page:

use App\Models\Category as TreePageModel;
use SolutionForest\FilamentTree\Concern\TreeRecords\Translatable;
use SolutionForest\FilamentTree\Pages\TreePage as BasePage;

class Category extends BasePage
{
    use Translatable;

    protected static string $model = TreePageModel::class;

    public function getTranslatableLocales(): array
    {
        return ['en', 'fr'];
    }

    protected function getActions(): array
    {
        return [
            LocaleSwitcher::make(),
        ];
    }
}
