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.

You can install the package via composer:

composer require codewithdennis/filament-select-tree

php artisan filament:assets

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')

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])

Allow soft deleted items to be displayed

->withTrashed()

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')

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());
        })
])
