222245Rendering the form
223246------------------
224247
225- Coming Soon. Still a work in progress.
248+ Polycollections require manual work to render. This code can go
249+ in the same template that renders the rest of the form.
250+
251+ You will need to render add buttons from the prototypes array, which is
252+ keyed on the _ type field in the form definition.
253+
254+ It is best illustrated by example.
