Thank you,
here is my code at the beginning of that view file:

<?php
if(empty($this->element->characteristics))
return;
?>
<?php
$mainCategory = reset($this->categories);
if($mainCategory->category_id == 48)
$this->params->set('characteristic_display', 'list');
?>
<div id="hikashop_product_characteristics" class="hikashop_product_characteristics">
<?php
if($this->params->get('characteristic_display') != 'list') {
$app = JFactory::getApplication();
$config = hikashop_config();
$characteristics_dynamic_display = $config->get('characteristics_dynamic_display', 1);
$this->characteristics=&$this->element->main->characteristics;
it works, but list view is viewed as on attached picture. The characteristics block is viewed two times and text "cena" (english price) have big font.
