Currently, in my minicart.phtml override file I have knockout.js code like this to display the number of items in my cart:
<!-- ko if: getCartParam('summary_count') --> <!-- ko text: getCartParam('summary_count') --><!-- /ko --> <!-- ko i18n: 'items' --><!-- /ko --> <!-- /ko -->
If an item is added to my cart I also want to display the current cart subtotal. Is there a method for directly displaying this with knockout.js or is there another simpler way to achieve this? How do I find out what other things I can display with knockout.js?
