I am currently implementing Angular's ng-repeat to showcase products from a JSON feed. My goal is to organize and categorize these products by distinguishing between free items (with the JSON property 'free':true) and those that require a purchase. I want to prioritize displaying the free items first and then the purchasable ones. It would be really beneficial if this sorting functionality could be accomplished using the orderBy feature. Thank you in advance for any assistance with this. -Ryan
