Display entries by category (multiple categories)

Question

I would like to know how I can create a page that contains all entries from a section e.g. 'news'. I want to divide the entries by their given category.

News (section)

Category 1:

• entry in category 1
• second entry in category 1
• third entry in category 1

Category 2:

• entry in category 2
• second entry in category 2
• third entry in category 2

etc.

Does anyone know the code for this? The categories are all in the same category group.

Answer 1

You can use .relatedTo(category)

{% for category in craft.categories.group('categoryName') %}
  <h2>{{category.title}}</h2>
  {% for entry in craft.entries.section('news').relatedTo(category) %}
    <a href="{{entry.url}}">{{entry.title}}</a><br>
  {% endfor %}
{% endfor %}

You can check for length if you don't want to show categories which aren't related to any entry.

See the relations documentation
