How to make 'Relation' field taggable?

[khalid3bdallah]

TL;DR
Any idea how to make 'Relation' field 'taggable' like 'Select' field?

---

In Select field, I can use taggable() function to allow me to add more options that doesn't already exist.

Select::make('tags')
      ->fromModel(Tag::class, 'name', 'name')
      ->taggable()
      ->multiple()

In 'Relation' class, 'taggable()' function doesn't exist.

Any idea how to implement this?

I am also facing this issue. Did you find any solution?

I have done this with this method.

In layout() method:

Select::make('locator.permitted_domains.')
                        ->fromModel(PermittedDomain::class, 'name')
                        ->title('Permitted Domains')
                        ->taggable()
                        ->multiple()
                        ->required(),

in createOrUpdate() method:

 // Save or Update Locator
        $locator->fill($request->get('locator'))->save();

        // Remove new values
        $permittedDomainIds = array_filter($request->input('locator.permitted_domains', []), function ($v, $k) {
            return filter_var($v, FILTER_VALIDATE_INT) !== false;
        }, ARRAY_FILTER_USE_BOTH);

        $locator->permitted_domains()->sync($permittedDomainIds);

        // Remove already existed values
        $newPermittedDomainsList = array_filter($request->input('locator.permitted_domains', []), function ($v, $k) {
            return is_string($v) && filter_var($v, FILTER_VALIDATE_INT) === false;
        }, ARRAY_FILTER_USE_BOTH);

        // Create new Permitted Domain
        if (count($newPermittedDomainsList) > 0) {
            $permittedDomain = [];
            foreach ($newPermittedDomainsList as $newPermittedDomain) {
                $permittedDomain[] = new PermittedDomain(['name' => $newPermittedDomain]);
            }

            $locator->permitted_domains()->saveMany($permittedDomain);
        }
