Build structured navigation menus in Filament.

This plugin for Filament provides a Navigation resource that lets you build structural navigation menus with a clean drag-and-drop UI.

Installation

Begin by installing this package via Composer:

composer require ryangjchandler/filament-navigation

Run migrations.

php artisan migrate

Publish the package's assets:

php artisan filament:assets

Usage

You first need to register the plugin with Filament. This can be done inside of your PanelProvider, e.g. AdminPanelProvider.

use RyanChandler\FilamentNavigation\FilamentNavigation;

return $panel
    ->plugin(FilamentNavigation::make());

If you wish to customise the navigation group, sort or icon, you can use the NavigationResource::navigationGroup(), NavigationResource::navigationSort() and NavigationResource::navigationIcon() methods.

Data structure

Each navigation menu is required to have a name and handle. The handle should be unique and used to retrieve the menu.

Items are stored inside of a JSON column called items. This is a recursive data structure that looks like:

[
    {
        "label": "Home",
        "type": "external-link",
        "data": {
            "url": "/",
            "target": "_blank",
        },
        "children": [
            // ...
        ],
    }
]

The recursive structure makes it really simple to render nested menus / dropdowns:

<ul>
    @foreach($menu->items as $item)
        <li>
            {{ $item['label'] }}

            @if($item['children'])
                <ul>
                    {{-- Render the item's children here... --}}
                </ul>
            @endif
        </li>
    @endforeach
</ul>

Retrieving a navigation object

To retrieve a navigation object, provide the handle to the RyanChandler\FilamentNavigation\Models\Navigation::fromHandle() method.

use RyanChandler\FilamentNavigation\Models\Navigation;

$menu = Navigation::fromHandle('main-menu');

Custom item types

Out of the box, this plugin comes with a single "item type" called "External link". This item type expects a URL to be provided and an optional "target" (same tab or new tab).

It's possible to extend the plugin with custom item types. Custom item types have a name and an array of Filament field objects (or a Closure that produces an array) that will be displayed inside of the "Item" modal.

This API allows you to deeply integrate navigation menus with your application's own entities and models.

return $panel
    ->plugin(
        FilamentNavigation::make()
            ->itemType('post', [
                Select::make('post_id')
                    ->//...
            ])
    );

All custom fields for the item type can be found inside of the data property on the item.

Global custom fields

There might be cases where you want all item types to have an additional set of fields. This is useful for classes, custom IDs and more.

To register global custom fields, use the withExtraFields() method on the plugin object.

return $panel
    ->plugin(
        FilamentNavigation::make()
            ->withExtraFields([
                TextInput::make('classes'),
            ]),
    );

The Navigation field type

This plugin also provides a custom Filament field that can be used to search and select a navigation menu inside other forms and resources.

use RyanChandler\FilamentNavigation\Filament\Fields\NavigationSelect;

->schema([
    NavigationSelect::make('navigation_id'),
])

By default, this field will not be searchable and the value for each option will be the menu id.

To make the field searchable, call the ->searchable() method.

->schema([
    NavigationSelect::make('navigation_id')
        ->searchable(),
])

If you wish to change the value for each option, call the ->optionValue() method.

->schema([
    NavigationSelect::make('navigation_id')
        ->optionValue('handle'),
])
