I understand that community topics are not hierarchical and it is a flat list. What I wonder is, how can they be grouped by theme? For instance, here on Zendesk's community, they have blocks of topics. Interestingly, they also have some KB sections in there I believe.
Is the below page template simply a static list of links? I want to achieve something similar, but a static list would be bad, because I want to display post counts, which would require the metadata provided by the helper.
