We built a lot of content blocks in Uber template based on JA ACM module. Here is the step to create a content block with JA ACM Module.

Step 1 - Create JA ACM module

From your site back-end, go to: Extensions > Module Manager, hit the "New" button to create module then select JoomlArt Advanced Custom Module

Step 2 - Select position, pages to display the module

Step 3 - Select type

The module supports many types, each type has multiple styles. Once you select type, the corresponding setting fields are loaded. For each type, it includes sample data by default that help you understand the structure of content block. Now you can change setting of the fields, add content, etc.

We use ACM to build views for the supported content types in JA Charity: Joomla Article default, Video, Event and Gallery. So for each content type, we build separate views and styles.

JA ACM module content type structure

Each content type of JA ACM module is a folder stored in templates\ja_charity\acm\.

templates/ja_charity/acm/
+--news-featured/
¦    +-- config.xml				/*define fields for the content type*/
¦    +-- tmpl/
¦    ¦  +-- carousel.php
¦    ¦  +-- carousel.xml
¦    ¦  +-- event-slider.php
¦    ¦  +-- event-slider.xml
¦    +-- less/
¦    ¦  +-- style.less
¦    ¦  +-- event-slider.less
¦    +-- css/
¦    ¦  +-- style.css
¦    +-- js/
¦    +-- images/
+--events/
+--features-intro/
+--videos/
+--gallery/
+--countdown/
+--slideshow/

In each folder, it includes:

• config.xml file: define title and description about the content type
• tmpl folder: include all style files that the content type support. Each style has one .xml file (define fields in the style) and a .php file (define how the fields defined in the .xml file displayed in front-page).
• less folder: include .less files to style for the content type and each style.
  
• css folder: the compiled CSS file from the .less files, all files are joined so you just have style.css in this folder.
• .js folder (if necessary): include JavaSripts files for the content type.

1. Customize style

You can customize style for any content block and style that the content block supports. Open .less file in the less folder of the content type, for example: acm/news-featured/less/style-1.less then go ahead with your customization. Once done, please save the file and compile LESS to CSS via JA Teline V template style admin panel.

Please do not use .css files to customize as the file is overridden any time you compile LESS to CSS.

Create new fields for a style

You can add new fields for any type, open the .xml file of the style (example: acm/news-featured/tmpl/style-1.xml)then define new fields using the format below:

<field name="button" type="text" default="" label="FIELD_LABEL" description="FIELD_DESC" required="1" />

2. Create new style for a type

For example, I want to create a new style (style 1) for the news-featured so I have to create the following files:

• Create .xml file - acm/news-featured/tmpl/style-1.xml
• Create .php file - acm/news-featured/tmpl/style-1.php
• Create .less file - acm/news-featured/less/style-1.less

The best way to create new style for a type is cloning files of an existing style.

3. Create new type

You can create new content type to build content for your site. For example, I want to create media content type, then I will follow the steps below:

• Step 1 - create acm/media/ folder
• Step 2 - create acm/media/tmpl folder, add style files for the content type (style-1.php, style-1.xml) then add fields and call the fields, define layout, class for fields in each style
• Step 3 - create acm/media/less folder, add .less files (style.less, style-1.less) and add style for the content block, styles.
• Step 4 (if required) - acm/media/js folder, add script.js file and add JavaScripts that is used for the content block.
