how focus right text field on custom form field template

hi there , tell this is very dificult to me becouse i am spanish language mother.
well i made the next form

public function VentaEmpresaForm()
	{
		$this->form->addText('cliente_id', 'Cliente')
			->setAttribute('placeholder', 'Seleccione el cliente')
			->addRule(Form::MAX_LENGTH, 'Maximo de caracteres %d',100)
			->addRule(Form::PATTERN, 'Solo puede usar números, letras, espacios y puntos','[a-zA-ZñÑ0-9. ]+');

		$this->form->addText('estado', 'Estado')
			->setRequired('Estado de la venta venta')
			->setAttribute('placeholder', 'Estado de la venta')
			->addRule(Form::MAX_LENGTH, 'Maximo de caracteres %d',100)
			->addRule(Form::PATTERN, 'Solo puede usar letras numeros y espacio','[a-zA-ZñÑ0-9 ]+');


		$prod_raw=[
                    '{"1":3.5}'=>"Hielo grande",
                    '{"2":2.5}'=>"Hielo pequeño",
                    '{"3":3.5}'=>"Agua",
                ];


                $this->form->addCheckboxList('productos_raw', 'Producto Raw', $prod_raw);

                $this->form->addHidden('producto_id');
                $this->form->addHidden('preciounitario');


                $this->form->addText('cantidad', 'Cantidad')
			->setAttribute('placeholder', 'Cantidad del producto')
			->addRule(Form::MAX_LENGTH, 'Maximo de caracteres %d',45)
			->addRule(Form::PATTERN, 'Solo puede usar números','[0-9]+');

		$this->form->addText('observaciones', 'Observaciones')
			->setAttribute('rows', 4)
			->setAttribute('placeholder', 'Por favor ingrese las observaciones de la venta')
			->addRule(Form::MAX_LENGTH, 'Maximo de caracteres %d',250)
			->addRule(Form::PATTERN, 'Solo puede usar letras, numeros, signos + - /','[a-zA-ZñÑ0-9. +-/]+');


		if(!$this->presenter->getParameter('postId'))
		{
			$this->form->addSubmit('send', 'Realizar Venta');
		}
		else
		{

			$this->form->addSubmit('send', 'Editar Venta');
		}

		$this->form->onSuccess[] = callback($this, 'VentaEmpresaProcess');
		return $this->form;

and i made a dynamic template form

{foreach $form['productos_raw']->items as $key => $item}
    {var $nombreid = str_replace(' ', '', $item)}
    {var $productoid = 'producto'.$nombreid}
    <label>
        <input n:name="productos_raw:$key" id="{$nombreid}" onchange="insertarProducto({$nombreid})"> {$item}
    </label>
    <div id="producto{$nombreid}" style="display:none;" class="form-group" onmouseover="divFocus({$productoid})">
    <span n:ifset="$form['productos_raw']->errors[0]" style="color:red; font-size:small; opacity:0.4;">
        {$form['productos_raw']->errors[0]}
    </span>
    {input $form['producto_id']->name name=>"{$form['producto_id']->name}[]", id=>"{$form['producto_id']->name}", class=>"form-control"}
    {input $form['preciounitario']->name name=>"{$form['preciounitario']->name}[]", id=>"{$form['preciounitario']->name}", class=>"form-control"}
    {input $form['cantidad']->name name=>"{$form['cantidad']->name}[]", id=>"{$form['cantidad']->name}", class=>"form-control", type=>"number",min=>"1", onchange=>"obtenerMonto()"}
    {input $form['observaciones']->name name=>"{$form['observaciones']->name}[]", id=>"{$form['observaciones']->name}", class=>"form-control"}
    </div>
{/foreach}

if you see on template i declare text fields as arrays instead of regular field

name=>"{$form['producto_id']->name}[]"

the question is when i type a incorrect key (like return key) it show me the error alert But as there are several fields with the same name (with[]) the focus goes to the first one of the same name Although I was wrong in the second one, how can i made that the focus goes to the one that i made the wrong input

i hope that you understand me
