Example template, with inheritance : : CMS Made Simple 2.x Official Documentation

Example template, with inheritance

Template Inheritance uses a 'parent' or 'base' template that contains the basic elements of your site and defines blocks that 'child' templates will override.

Below is a basic Parent/Base template created using a 'Core::Page' template type in Design Manager.
This is a simple layout with just one column. Template Inheritance allows child templates to build upon this.
This template should not be used as a page template. Only child templates should be used in the Content Manager.

The CSS code from the Basic Example Template can be used with this template. It should be pasted into a new stylesheet called 'CustomCSS' in Design Manager/Stylesheets.
The 'CustomCSS' stylesheet should be added to the default design in Design Manager/Designs.

Child Template 1. Full Width Content Column

Blocks in child templates will either add-to or replace blocks of the same name in parent templates. The rest of the code from the parent template, that isn't in blocks, will be inherited as-is.
A child template is created using a 'Core::Page' template type in Design Manager.
This template will inherit all the code of the parent template except the 'title' block, which gets replaced.

 <!-- This template will keep everything from the Parent template except the 'title' block. -->
{extends file='cms_template:Base Page Template'}
{block name='title'}My Page Title{/block}<!-- This Title text will replace the 'title' block in the Parent template. -->

Child Template 2. Two Columns - Content and Sidebar

In this child template a new content field is added (appended) to the 'top' block using a second content tag.
The original content tag and the second content tag get used in the 'content' block. The 'title' block gets replaced.
This child template will inherit the rest of the code from the parent template.

 <!-- This template will keep everything from the Parent template except the 'title' block, and add a sidebar column. -->
 {extends file='cms_template:Base Page Template'} {block name='title'}My Page Title{/block}
<!-- This Title text will replace the 'title' block in the parent template. -->
 {block name='top' append}
<!-- The contents of this block will be added (appended) to the 'top' block in the parent template. -->
 {$content2 = "{content block='content2'}" scope=global} {/block} {block name='content'}
<!-- The contents of this block will replace the 'content' block in the parent template. -->
<div class="row">
	<!--  Main column content. -->
	<div class="col-8">
		<article>
		<h2>{title}</h2>
		<!-- Title of the page is from 'Content/Content manager/Page_Name' Title field -->
		 {$content} 
		<!-- Page content is from 'Content/Content manager/Page_Name' Content field -->
		</article>
	</div>
	<!-- Sidebar column content. -->
	<div class="col-4">
		<aside>{$content2}</aside>
	</div>
</div>
{/block}

Child Template 3. Two Columns - Content and Sidebar + Hero Banner Image + jQuery

In this child template the second content field is added (appended) to the 'top' block plus a content_image field to be used as a hero banner.
The original content tag, the second content tag and the content_image get used in the 'content' block. The 'title' block gets replaced.
This child template introduces new content for the 'jquery' block, which is empty in the parent template.

 <!-- Same as Child Template 2, with a Hero Banner image and adding jQuery. -->
 {extends file='cms_template:Base Page Template'} {block name='title'}My Page Title{/block}
<!-- This Title text will replace the 'title' block in the parent template. -->
 {block name='top' append}
<!-- The contents of this block will be added (appended) to the 'top' block in the parent template. -->
 {$HeroBanner = "{content_image block='HeroBanner'}" scope=global} {$content2 = "{content block='content2'}" scope=global} {/block} {block name='content'}
<!-- The contents of this block will replace the 'content' block in the parent template. -->
<div class="row">
	<div class="col-12 center">
		{$HeroBanner}
	</div>
	<!-- Hero Banner Image content. -->
</div>
<div class="row">
	<!--  Main column content. -->
	<div class="col-8">
