<a href={{ child_page.url }}>{{ child_page.title }}</a>
{% endfor %}

Code
{% for child_page in page.children limit:2 %}
<a href={{ child_page.url }}>{{ child_page.title }}</a>
{% endfor %}

<a href=/parent/child1/>Child 1</a>
<a href=/parent/child2/>Child 2</a>
offset

Code
{% for child_page in page.children offset:1 %}
<a href={{ child_page.url }}>{{ child_page.title }}</a>
{% endfor %}
Output
<a href=/parent/child2/>Child 2</a>
<a href=/parent/child3/>Child 3</a>
range
Defines a range of numbers to loop through.
Code
{% assign n = 4 %}
{% for i in (2..n) %}
{{ i }}
{% endfor %}
{% for i in (10..14) %}
{{ i }}
{% endfor }}
Output
2 3 4
10 11 12 14
reversed
Iterates through the loop in reverse order, starting from the last item.
Code
{% for child_page in page.children reversed %}
<a href={{ child_page.url }}>{{ child_page.title }}</a>
{% endfor %}
Output
<a href=/parent/child3/>Child 3</a>
<a href=/parent/child2/>Child 2</a>
<a href=/parent/child1/>Child 1</a>
cycle
Loops through a group of strings and outputs them in the order that they were passed as parameters. Each time cycle is called, the next string that was passed as a parameter is output.
Code
{% for item in items %}
<div class={% cycle 'red', 'green', 'blue' %}> {{ item }} </div>
{% end %}
Output
<div class=red> Item one </div>
<div class=green> Item two </div>
<div class=blue> Item three </div>
<div class=red> Item four </div>
<div class=green> Item five</div>
