I'm working on a students directory with the following structures:

Directory (parent category)
|_ 2017-2016 (child category)
|_ 2016-2015 (child category)
|_ 2015-2014 (child category)

In each child category there are articles about a student (his resume).

I'm using a List All Categories menu type to display all child categories. I could override the layout of this List All Categories view.

Now what I would like is to override the layout of the Category Blog view used by child categories without having to create a menu for each child category.

So I've duplicated:


I've rename each new files to have the following:


And I've changed the test.xml (changing BLOG by TEST):


In the test.xml file I've changed nothing else.

Then for each child category under Options tab I've chosen my new test layout.

In frontend, the articles of child categories (student resume) don't display. Instead I have the message saying there is no article in this category.

For each child category when choosing default Blog or List layout, articles are correctly displayed.

Could you please help me finding what I have missed.

Tahnk you

  • Did you also change default="blog" to default="test" in the xml file? If so, did you manage to get your category overrides to display as you wanted? I'm still struggling with a similar issue.

Not 100% sure if I got you right because there are quite a few questions in one which I am not able to see what the relation is.

But if I got you right it could be just the following setting:

Menu > Your Item > Blog Layout > Include Subcategories 

Choose 'All' there.

Apart from that your override files should not be located in the Joomla! component folder itself. They should be based in your Templates HTML folder like this:


If this two things are not answering your questions, please specify what is working already and what not. Especially why you think you need an override for this at all is not really clear to me.

  • Hello, thank you for your reply. Articles of child categories are displayed from category blog list (when you click an article title). Not from a menu. I would like to avoid creating a hidden menu for each article. I think my default category options are good because, when I go back to core Blog or List layout in each child category (Options tab), articles are displaying normally. I've followed your suggestion and tried with override files located in my template. Same result : I've got the message "Threre is noarticle in this category".

  • Sorry If I was confuse while trying to explain the context of my problem. To be more precise I would like to know why my custom override doesn't display any article while it appears correctly in category layout list and while it is a perfect copy of the default Blog layout. Only the name was changed.
