Multi-select a BelongsToMany

In the example I have a Note and Tags, where the Tas have a BelongsToMany relation.

I wasn't able to store the selected Tag id's in the separate note_tag table therefore added an extra column in the Note model where the id's are stored of the selected tags.

So I get all tags:

public function fields(Request $request)
    {
        $tags = \App\Tag::all()->pluck('name', 'id');

Then

Multiselect::make('Tags', 'tags')
                ->options($tags)
                ->placeholder('Kies een of meerdere tags'),

That worked for me nevertheless I can't add the tags column to the search as it stores the id's. And using a filter with dynamic values is not working as well.

I've changed my Tags table to:

Schema::create('tags', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('key');
            $table->string('value');
            $table->timestamps();
        });

Using the following stores the vales instead of the ids

public function fields(Request $request)
    {
        $tags = \App\Tag::all()->pluck('key', 'value');

Now you can use search on the tags as well.

This is an old thread, but I just happened to resolve the very same problem in Nova.

We can simply use the searchable method:

use Laravel\Nova\Fields\BelongsToMany;

BelongsToMany::make('Your Field')->searchable();
