Thanks for that answer. Do you have any examples of creating standalone funnelback freemarker macros? here is an example I am using within the .ftl
<h3>Short courses</h3>
<@fb.MultiFacet name="Short_courses">
<@fb.MultiCategories facet=fb.facet />
</@fb.MultiFacet>
Still spits out a radio button instead of a checkbox...
