class Download extends Page
{
    protected static string | \BackedEnum | null $navigationIcon = Heroicon::OutlinedDocumentText;
 
    protected string $view = 'filament.pages.download';
 
    public ?array $data = [];
 
    public function mount(): void
    {
        $this->form->fill();
    }
 
    public function form(Schema $schema): Schema
    {
        return $schema
            ->components([
                DatePicker::make('trade_date')
                    ->minDate(now()->subMonths(2)->startOfMonth())
                    ->maxDate(today()),
                Select::make('customer')
                    ->required()
                    ->options(Customer::pluck('name', 'id')),
            ])
            ->statePath('data');
