After a series of 4 episodes published in the previous editions of the Joomla Community Magazine, hopefuly you already know a lot about Custom Fields.

But learning is a continuous process and it is always nice to learn from each other. This is exactly what I like about the Joomla Community: the fact that many people share their knowledge and enthousiasm.

So it is now time to share with you the list of resources that we have gathered over time (my apologies if I have missed some. If so, just drop me a line and I will be happy to update the list).

For example, did you know that Custom Fields were on the agenda of more than 20 JoomlaDays / conferences around the world ?

Click on the links below and you will know everything !

General resources

First things first : the official website of Joomla Documentation 

• https://docs.joomla.org/J3.x:Adding_custom_fields

Joomla Extension Directory

• beginning 2018, a new Category called "Custom Fields" has been added to the JED (Joomla Extensions Directory), which is an excellent thing
  https://extensions.joomla.org/category/authoring-a-content/custom-fields/
  (but note that not all authors have moved their extension to that Category, especially if the main purpose of the extension fits better in another Category)

Joomla User Group New Jersey (17/02/2022 - EN)

• Joomla 4 custom fields are rendered in a list fashion when presented on a public site, alongside articles for instance.
  Even though they can be grouped in the administrator console, the output does not reflect those groupings.
  What could we do to improve the page layout for those custom fields and maximise accessibility?
  Overrides are a powerful way to tweak the layouts already provided by Joomla. In a few more examples, learn from an override expert how easily you can make Joomla 'work' for your site.
