<h1 id="looping-through-jekyll-collections">Looping Through Jekyll Collections</h1>
<p>2022-08-12</p>
<p>I recently needed to add a couple new items to my wife&#8217;s personal recipe website (<a href="https://cookingwith.casa">cookingwith.casa</a>) which I hadn&#8217;t touched in quite a while. The Jekyll build still worked fine, but I realized I was statically adding each <code>collection</code> by hand on the main homepage[^1].</p>
<p>Not so good.</p>
<p>Of course, this wasn&#8217;t difficult at all to fix. Now everything is much more &#8220;hands free&#8221; moving forward. I figured I would share the details here in the hopes that others mind find it useful. Plus, it&#8217;s my blog - so I&#8217;ll do what I want!</p>
<h2 id="looping-our-collections">Looping Our Collections</h2>
<p>We want Jekyll to make things as streamlined as possible for us. This means that if I decide to add a new collection it will automatically render it along the others on the homepage.</p>
<p>Work smart not hard!</p>
<p>Let&#8217;s take a look at the bare-bones collections loop:</p>
<pre><code>{% for collection in site.collections %}
    &#60;!-- Our code goes here --&#62;
{% endfor %}
</code></pre>
<p>Then we need to include an <code>if</code> statement to avoid pulling in standard <code>post</code> items (or leave this in if that is desired):</p>
<pre><code>{% for collection in site.collections %}
    {% if collection.label != &#39;posts&#39; %}
    {% endif %}
{% endfor %}
</code></pre>
<p>Now for my specific use case, we want to display each collection label and then list its corresponding items below that label (see the <code>site[collection.label]</code> for reference)</p>
<pre><code>{% for collection in site.collections %}
    {% if collection.label != &#39;posts&#39; %}
        &#60;h2&#62;{{ collection.label }}&#60;&#47;h2&#62;
        &#60;ul class="recipe-list"&#62;
        {% for item in site[collection.label] %}
            &#60;li&#62;
                &#60;a href="{{ item.url }}"&#62;{{ item.title }}&#60;&#47;a&#62;
            &#60;&#47;li&#62;
        {% endfor %}
        &#60;&#47;ul&#62;
        &#60;hr&#62;
    {% endif %}
{% endfor %}
</code></pre>
<p>That&#8217;s it! Now if I plan to add any new collections down the line, I just need to include it in the <code>_config.yml</code> file and I&#8217;m set. The homepage will take care of the rest once rendered.</p>
<p>Enjoy looping through your Jekyll collections!</p>

<li>Just the sections were statically rendered. All the recipes were pulled in dynamically - I&#8217;m not that insane!</li>
