Сам себе и отвечаю :). Проверено на ocStore-2.1.0.1
Если кому надо - для отображения подкатегорий в списке категорий, т.е. сразу видим раскрытый список категорий, нужно исправить 2 файла в стандартной теме.
The Controller: catalog/controller/module/category.php
<?php
class ControllerModuleCategory extends Controller {
public function index() {
$this->load->language('module/category');
$data['heading_title'] = $this->language->get('heading_title');
if (isset($this->request->get['path'])) {
$parts = explode('_', (string)$this->request->get['path']);
} else {
$parts = array();
}
if (isset($parts[0])) {
$data['category_id'] = $parts[0];
} else {
$data['category_id'] = 0;
}
if (isset($parts[1])) {
$data['child_id'] = $parts[1];
} else {
$data['child_id'] = 0;
}
$this->load->model('catalog/category');
$this->load->model('catalog/product');
$data['categories'] = array();
$categories = $this->model_catalog_category->getCategories(0);
foreach ($categories as $category) {
$children_data = array();
//if ($category['category_id'] == $data['category_id']) {
$children = $this->model_catalog_category->getCategories($category['category_id']);
foreach($children as $child) {
$filter_data = array('filter_category_id' => $child['category_id'], 'filter_sub_category' => true);
$children_data[] = array(
'category_id' => $child['category_id'],
'name' => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'href' => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])
);
}
//}
$filter_data = array(
'filter_category_id' => $category['category_id'],
'filter_sub_category' => true
);
$data['categories'][] = array(
'category_id' => $category['category_id'],
'name' => $category['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
'children' => $children_data,
'href' => $this->url->link('product/category', 'path=' . $category['category_id'])
);
}
if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/module/category.tpl')) {
return $this->load->view($this->config->get('config_template') . '/template/module/category.tpl', $data);
} else {
return $this->load->view('default/template/module/category.tpl', $data);
}
}
}
The View file: catalog/view/theme/default/template/module/category.tpl
<div class="list-group">
<?php foreach ($categories as $category) { ?>
<?php //if ($category['category_id'] == $category_id) { ?>
<a href="<?php echo $category['href']; ?>" class="list-group-item active"><?php echo $category['name']; ?></a>
<?php if ($category['children']) { ?>
<?php foreach ($category['children'] as $child) { ?>
<?php if ($child['category_id'] == $child_id) { ?>
<a href="<?php echo $child['href']; ?>" class="list-group-item active"> - <?php echo $child['name']; ?></a>
<?php } else { ?>
<a href="<?php echo $child['href']; ?>" class="list-group-item"> - <?php echo $child['name']; ?></a>
<?php } ?>
<?php } ?>
<?php } ?>
<?php /*} else { ?>
<a href="<?php echo $category['href']; ?>" class="list-group-item"><?php echo $category['name']; ?></a>
<?php }*/ ?>
<?php } ?>
</div>
