Using a Layout Template

Renders current template inside a layout template from the template roots.

{% layout 'footer.liquid' %}

Whe the extname option is set, the above .liquid extension can be omitted and writes:

{% layout 'footer' %}

When a partial template is rendered by layout, the code inside it can access its caller’s variables but its parent cannot access variables defined inside a included template.

Passing Variables

Variables defined in current template can be passed to a the layout template by listing them as parameters on the layout tag:

{% assign my_variable = 'apples' %}
{% layout 'name', my_variable: my_variable, my_other_variable: 'oranges' %}

Blocks

The layout file can contain multiple blocks which will be populated by the child template (the caller). For example we have a default-layout.liquid file with the following contents:

Header
{% block content %}My default content{% endblock %}
Footer

And it’s called by a page.liquid file with layout tag:

{% layout "default-layout" %}
{% block content %}My page content{% endblock %}

The render result of page.liquid will be :

Header
My page content
Footer

Block

• Multiple blocks can be defined within a layout template;
• The block name is optional when there's only one block.
• The block contents will fallback to parent's corresponding block if not provided by child template.
