Related questions about your Joomla site development and customization


The docs is for templates developed with JA T3v2 Framework such as JA Zite, JA Travel, etc.

Here is the explanation about themes: Base theme and Theme variations - your override theme.

Base theme

Base theme is defined in JAT3 plugin and you're right, it locates in: plugins/system/jat3/jat3/base-themes/. It holds very basic layout design.

Theme variations

This is your custom theme and all of its file should be added to: /templates/ja_zite/themes/custom_theme/ folder. This theme will override the above base theme in core plugin. The following is file/folder would be included in your override theme:

  • "blocks" folder to hold the blocks you want to override
  • "css" folder to hold template.css to override general template styling and menu folder to override menu systems styling
  • "html" folder to override same files in the core plugin for content components and modules views
  • "images" folder to override the logo and generally all graphics needed to have a custom theme design
  • "info.xml" file to hold theme information

If you don't want to override one of above file/folder, your override theme will inherit from core plugin.


I notice that there are 2 cache settings, one in Global configuration and one in Template setting. Do they conflict when they are both enabled.

cache setting


No, they don't conflict. You can enable both Cache setting in Global configuration and in Template setting.

Template cache (T3 framework) uses page cache (like System - Cache plugin), meanwhile Cache in Global Configuration is module cache. Even though, these cache modes are different, you can apply both on your site. Check out more information at Joomla caching explained.

With the cache in Global Configuration enabled, you can see two options:

  • ON - Conservative caching
  • ON - Progressive caching

Conservative level refers to smaller system cache, meanwhile Progressive level (default) is for faster, bigger system cache, includes module renderers cache (however, not appropriate for extremely large sites).

By default, editor like JCE strips some HTML tags, so please go to "Global configuration" and disable editor by setting "Default Editor" to "None".

I want to make one menu item invisible, but I want to keep the URL.

Templates developed with JA T3v2 framework

For main menu ite: open the menu item you want to make it invisible, in the tab "Parameters (JA Extended)", add class to the field "Additional class". In this tutorial, we add class: invisible.

default editor

Next, open the template.css to add style for the additional class above.

#ja-mainnav .ja-megamenu .megamenu li.invisible {
display: none;

For sub-category, do the same way. For example, we add class sub-invisible. So we'll add the following css rule to the template.css.

#ja-mainnav .megamenu li.sub-invisible {
display: none;

Templates developed with T3 framework

As T3 integrated Bootstrap so you can use the hidden class of Bootstrap. Here is the steps:

Open the Megamenu setting panel, select the menu item you want to make it invisible then add the following class to the "Extra class" field.

default editor

For templates supports Bootstrap 3 version

hidden-lg hidden-md hidden-sm hidden-xs

The menu item is invisible in Large, medium, small and extra small layouts. Find more info of Bootstrap 3 responsive utilities at: http://getbootstrap.com/css/#responsive-utilities

For templates support Bootstrap 2

If your template use Bootstrap 2, use the class:

hidden-desktop hidden-table hidden-phone

For more info, please check the Bootstrap 2 Responsive utility classes.

Many users are concerned if they can migrate their JA T3v2 framework templates such as JA Travel, JA Community Plus... to T3 Framework template such as JA Sugite, JA PLaymag... The answer is NO. JA T3v2 framework and T3 framework are independent, the style class system is also different.

T3 Framework is developed with LESS and integrates Bootstrap 2 and 3 then it's markup is far different from the JA T3v2 Framework.

There are templates that works with both JA T3v2 and T3 Framework? Yes, here is the list:

The templates have different packages, package for JA T3v2 Framework and Package for T3 framework, the 2 packages are different. In other words, they are different templates with same design.

How we implement it? We develop it from beginning as any other new template, there is no upgrade or migration.
