Recipe: use with spatie/laravel-tags

[cord]

UseCase: only pre-defined tags should be selectable no dynamic creation of tags should be possible as with https://novapackages.com/packages/spatie/nova-tags-field

// define type to select from

            $tagType = 'myType';

//(...)

            Multiselect::make(__("Tags"), 'tags')
