Description:

Selecting type in MorphTo field selection doesn't trigger dependsOn if a field is dependant on it.

$title = MorphTo::make('Title Type', 'title')
    ->types([
        Movie::class,
        Series::class,
    ])
    ->showCreateRelationButton()
    ->sortable()
    ->rules('required')
    ->searchable()
    ->help('The movie or series the quote belongs to'),

Text::make('Description')
    ->sortable()
    ->searchable()
    ->dependsOn($title, function(Text $field, NovaRequest $request, FormData $formData) {
        ray($formData->title_type); // Only triggers on load
        if ($formData->title_type != null) {
            return $field->show()->rules('required');
        } else {
            return $field->hide();
        }
    } )
    ->help('The description of the title'),

Yep, experiencing this behaviour too in Nova 5, Laravel 12.

Further to this, if you set the defaultResource on the MorphTo, it doesn't pre-populate the related DependsOn field

  public function fields(NovaRequest $request): array
    {
        return [
            BelongsTo::make('Vessel', 'vessel', Vessel::class)->searchable(),

            MorphTo::make('Model')->types([
                User::class,
            ])->defaultResource(User::class)
                ->searchable(),

            BelongsTo::make('Role', 'role', Role::class)
                ->dependsOn(['vessel', 'model'], function (BelongsTo $field, NovaRequest $request, FormData $formData) {

                    $vesselId = $formData->vessel;
                    $modelUuid = $formData->model;
                    
                    if ($vesselId && $modelUuid) {
                        $field->relatableQueryUsing(function (NovaRequest $request, Builder $query) use ($vesselId, $modelUuid) {
                            $query->whereDoesntHave('rolesPivot', function ($q) use ($vesselId, $modelUuid) {
                                $q->where('vessel_id', $vesselId)
                                    ->where('model_uuid', $modelUuid)
                                    ->where('model_type', 'user');
                            });
                        });
                    }
                }),
        ];
    }
