Introduction#
The official helper function list_categories is not sufficient, so I had to use the variable "categories" myself.
Since I haven't learned node.js, I had to experiment blindly.
First, I used console.log() to see the content of site.categories.data, which is as follows.
After some experimentation, I found that this object is called using map().
Output category titles#
<% site.categories.map(function(category){ %>
<h1><%= category.name %></h1>
<% }) %>
Output article titles#
<% site.categories.map(function(category){ %>
<h1><%= category.name %></h1>
<% category.posts.map(function(post){ %>
<h2><%= post.title %></h2>
<% }) %>
<% }) %>
