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 check 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>
    <% }) %>
<% }) %>
