I want to display the total items count using Knockout, in
Magento_Checkout::header/minicart.phtml, e.g. if I have 2 items with the same SKU in the basket then the total items count is 1.
I have tried using
data-bind="text: getCartParam('items_count')" but this returns the total quantity (i.e. 2).
I could use
<?php echo $this->helper('\Magento\Checkout\Helper\Cart')->getItemsCount(); ?> but I'd like to try and use a Knockout binding instead - is this possible?
