Filament: Order Shipping Address: Same as Billing

Here's the code of the form in the Resource:

Forms\Components\Section::make('Billing Details')
    ->columnSpan(1)
    ->schema([
        Forms\Components\TextInput::make('billing_address')
            ->placeholder('Address')
            ->hiddenLabel()
            ->required(),
        Forms\Components\TextInput::make('billing_postcode')
            ->placeholder('Postcode')
            ->hiddenLabel()
            ->required(),
        Forms\Components\TextInput::make('billing_city')
            ->placeholder('City')
            ->hiddenLabel()
            ->required(),
    ]),
Forms\Components\Section::make('Shipping Details')
    ->columnSpan(1)
    ->schema([
        Forms\Components\Checkbox::make('use_billing_address')
            ->live() 
            ->default(true)
            ->disabledOn('edit')
            ->label('Same as billing'),
        Forms\Components\Group::make([ 
            Forms\Components\TextInput::make('shipping_address')
                ->placeholder('Shipping Address')
                ->hiddenLabel()
                ->required(),
            Forms\Components\TextInput::make('shipping_postcode')
                ->placeholder('Shipping Postcode')
                ->hiddenLabel()
                ->required(),
            Forms\Components\TextInput::make('shipping_city')
                ->placeholder('Shipping City')
                ->hiddenLabel()
                ->required(),
        ])->hidden(fn (Forms\Get $get) => $get('use_billing_address')) 
    ])

The main parts are highlighted:

1. Checkbox with live()
2. Group with ->hidden() based on condition

Then, in the table, you may use placeholder() to show "Use billing address" if the shipping address is empty.

Tables\Columns\TextColumn::make('billing_address'),
Tables\Columns\TextColumn::make('shipping_address')
    ->placeholder('Use billing address'),
