+<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>
