Like in Shopify's liquid: "For" iterates over an array or collection. Several useful variables are available to you within the loop.

== Basic usage:

  {% for item in collection %}
    {{ forloop.index }}: {{ item.name }}
  {% endfor %}

== Advanced usage:

  {% for item in collection %}
    <div {% if forloop.first %}class="first"{% endif %}>
      Item {{ forloop.index }}: {{ item.name }}
    </div>
  {% else %}
    There is nothing in the collection.
  {% endfor %}

You can also define a limit and offset much like SQL. Remember that offset starts at 0 for the first item.

  {% for item in collection limit:5 offset:10 %}
    {{ item.name }}
  {% end %}

To reverse the for loop simply use {% for item in collection reversed %}

== Available variables:

forloop.name:: 'item-collection' forloop.length:: Length of the loop forloop.index:: The current item's position in the collection;

               forloop.index starts at 1.
               This is helpful for non-programmers who start believe
               the first item in an array is 1, not 0.

forloop.index0:: The current item's position in the collection

                where the first item is 0

forloop.rindex:: Number of items remaining in the loop

                (length - index) where 1 is the last item.

forloop.rindex0:: Number of items remaining in the loop

                 where 0 is the last item.

forloop.first:: Returns true if the item is the first item. forloop.last:: Returns true if the item is the last item. forloop.parentloop:: Provides access to the parent loop, if present.
