Custom Field Suite is a forked alternative to Advanced Custom Fields. The two work very similar so while looking for a way to render a series of fields for a post, I looked up ACF’s method and found it works great with CFS!
Here’s the ACF method: http://www.advancedcustomfields.com/resources/get_fields/
And here’s an adjusted gist version:
As you’ll see, ACF has a get() method so you use CFS()->get() with no parameters to get all custom fields for the current post. It’ll give you an array. And you just iterate over the array and get() each field by name, then render it.
