Despite being tremendously useful, template overrides for plugins are a type of override that is barely known in Joomla community.
There is no way to create this type of override from the Joomla backend. It is a completely manual process. Template overrides for plugins are intended for extensions that output content in frontend. This means just a few plugins are ready for this feature.
In this tutorial, we will show you how to easily create plugin overrides in Joomla.

CSS Grid #17: Nesting Grids
- Written by Jorge Montoya Jorge Montoya
- Published: 30 November 2018 30 November 2018
With CSS Grid, it is possible to turn a grid item into a grid itself and that way, nest a grid inside another grid. With this approach, you can break the design into different parts and layout each one of them individually.
This will provide you with the required flexibility when converting your designs to HTML/CSS. This tutorial will explain how to build nested grids with CSS Grid.
Let’s start!
CSS Grid #16: The grid-auto-flow: dense Property
- Written by Jorge Montoya Jorge Montoya
- Published: 27 November 2018 27 November 2018
In one of the first tutorials, you learned that items inside a grid are placed according to a row based flow by default. Items wrap over to the next row and are placed into grid areas if there’s enough space available.
If not, the item will jump over to the next slot, where it can fit. This could lead to a grid layout with empty spaces because the placement algorithm is placing the grid items according to a sequence. The grid-auto-flow: dense property will allow you to fill those empty spaces with grid items of the right size, independently of the source order of the document.
Let’s demonstrate this property with an example!
What are Multilingual Associations in Joomla?

Joomla has a component called "Multilingual Associations". This will make your life much easier if you build multi-lingual Joomla sites.
Before this component was added, there was no easy place to manage all of your translation items. Every translated item had to be found and edited individually. With the Multilingual Associations component, you will be able to edit all your translations in a single interface. This will save you a lot of time and energy.
How to Create Hidden Menu Items in Joomla

Since the beginning of Joomla, users have created hidden menu links. This is a neccesary workaround because menu links control many of the features on Joomla pages - even pages that don't show in menus.
One very common use case is to create links to special sales pages and landing pages. Sometimes we need a menu link to set up the page, but we don't want that link to be easily visible.
"Add Menu Title" is a menu option that makes it really easy to hide links. Here's how it works ...
CSS Grid #15. The justify-content and align-content Properties
- Written by Jorge Montoya Jorge Montoya
- Published: 07 November 2018 07 November 2018
In the previous CSS Grid tutorial, you learned about the align and justify properties to center and align items within a grid on the horizontal and vertical axes.
However, there are cases in which the total size of the grid is less than the size of the grid container. This happens because all items within the grid and the container itself are sized with fixed values (px, em, rem).
In such cases, it is necessary to align the tracks themselves, that is the whole grid, in order to exploit and fill up that additional empty space. In such a situation, you can make use of the align-content and justify-content properties. This is what I will explain in this tutorial.
