Hi,
For your HikaMarket questions, please use the HikaMarket forum section.
There is no restriction on the number of categories a product can have but you can create it manually.
In the "productmarket | form" view of HikaMarket, you will find the line
echo $this->categoryType->displayMultiple('data[product][categories]', @$this->product->categories, '', $this->rootCategory);
If you are replacing by
$cat = 0;
if(!empty($this->product->categories)) {
$cats = array_keys($this->product->categories);
$cat = reset($cats);
}
echo $this->categoryType->displayMultiple('data[product][categories]', @$this->product->categories, '', $this->rootCategory);
And it will display just one category (the first one).
Regards,
