The {% placeholder %} tag will render a placeholder section which is generally used inside Layouts. This tag will return any placeholder contents that have been added using the {% put %} tag, or any default content that is defined (optional).

{% placeholder name %}

Content can then be injected into the placeholder in any subsequent page or partial.

{% put name %}
    <p>Place this text in the name placeholder</p>
{% endput %}

Default placeholder content

Placeholders can have default content that can be either replaced or complemented by a page. If the {% put %} tag for a placeholder with default content is not defined on a page, the default placeholder content is displayed. Example placeholder definition in the layout template:

{% placeholder sidebar default %}
    <p><a href="/contacts">Contact us</a></p>
{% endplaceholder %}

The page can inject more content to the placeholder. The {% default %} tag specifies a place where the default placeholder content should be displayed. If the tag is not used the placeholder content is completely replaced.

{% put sidebar %}
    <p><a href="/services">Services</a></p>
    {% default %}
{% endput %}

Checking a placeholder exists

In a layout template you can check if a placeholder content exists by using the placeholder() function. This lets you to generate different markup depending on whether the page provides a placeholder content. Example:

{% if placeholder('sidemenu') %}
    <!-- Markup for a page with a sidebar -->
    <div class="row">
        <div class="col-md-3">
            {% placeholder sidemenu %}
        <div class="col-md-9">
            {% page %}
{% else %}
    <!-- Markup for a page without a sidebar -->
    {% page %}
{% endif %}

Custom attributes

The placeholder tag accepts two optional attributes — title and type. The title attribute is not used by the CMS itself, but could be used by other plugins. The type attribute manages the placeholder type. There are two types supported at the moment — text and html. The content of text placeholders is escaped before it's displayed. The title and type attributes should be defined after the placeholder name and the default attribute, if it's presented. Example:

{% placeholder ordering title="Ordering information" type="text" %}

Example of a placeholder with a default content, title and type attributes.

{% placeholder ordering default title="Ordering information" type="text" %}
    There is no ordering information for this product.
{% endplaceholder %}
