title: Hide category from navigation in bigcommerce
body: <p>I created a new category in my bigcommerce store. Now, I need to hide a this category from every page in the "main" site navigation, so that you cannot get to the page that displays the products in that category unless you are given the link.
  Then I need hide all the "main" site navigation from that new product page so that you cannot go to the "main" site unless you go directly to it.
  I know this is code customization, but unsure where to start. 
  Can anyone guide me on where and what to do?
  Thanks!</p>
