Filament Select Tree

This package adds a dynamic select tree field to your Laravel / Filament application, allowing you to create interactive hierarchical selection dropdowns based on relationships. It's handy for building selection dropdowns with various customization options.

Installation

You can install the package via composer:

composer require codewithdennis/filament-select-tree

php artisan filament:assets

Relationships

Use the tree for a BelongsToMany relationship

use CodeWithDennis\FilamentSelectTree\SelectTree;

SelectTree::make('categories')
    ->relationship('categories', 'name', 'parent_id')

Use the tree for a BelongsTo relationship

use CodeWithDennis\FilamentSelectTree\SelectTree;

SelectTree::make('category_id')
    ->relationship('category', 'name', 'parent_id')

Methods

Set a custom placeholder when no items are selected

->placeholder(__('Please select a category'))

Enable the selection of groups

->enableBranchNode()

Customize the label when there are zero search results

->emptyLabel(__('Oops, no results have been found!'))

Display the count of children alongside the group's name

->withCount()

Keep the dropdown open at all times

->alwaysOpen()

Set nodes as dependent

->independent(false)

Expand the tree with selected values (only works if field is dependent)

->expandSelected(false)

Set the parent's null value to -1, allowing you to use -1 as a sentinel value (default = null)

->parentNullValue(-1)

All groups will be opened to this level

->defaultOpenLevel(2)

Specify the list's force direction. Options include: auto (default), top, and bottom.

->direction('top')

Display individual leaf nodes instead of the main group when all leaf nodes are selected

->grouped(false)

Hide the clearable icon

->clearable(false)

Activate the search functionality

->searchable();

Disable specific options in the tree

->disabledOptions([2, 3, 4])

Hide specific options in the tree

->hiddenOptions([2, 3, 4])

Specify a different key for your model. For example: you have id, code and parent_code. Your model uses id as key, but the parent-child relation is established between code and parent_code

->withKey('code')

Filters

Use the tree in your table filters. Here's an example to show you how.

use Filament\Tables\Filters\Filter;
use Illuminate\Database\Eloquent\Builder;
use CodeWithDennis\FilamentSelectTree\SelectTree;

->filters([
    Filter::make('tree')
        ->form([
            SelectTree::make('categories')
                ->relationship('categories', 'name', 'parent_id')
                ->independent(false)
                ->enableBranchNode(),
        ])
        ->query(function (Builder $query, array $data) {
            return $query->when($data['categories'], function ($query, $categories) {
                return $query->whereHas('categories', fn($query) => $query->whereIn('id', $categories));
            });
        })
        ->indicateUsing(function (array $data): ?string {
            if (! $data['categories']) {
                return null;
            }

            return __('Categories') . ': ' . implode(', ', Category::whereIn('id', $data['categories'])->get()->pluck('name')->toArray());
        })
])
